/*
 * This file helps Angband work with Macintosh computers running OS X,
 * or OS 8/9 with CarbonLib system extention.
 *
 * To use this file, use an appropriate "Makefile" or "Project File", which
 * should define "MACINTOSH".
 *
 * The official compilation uses the CodeWarrior Pro compiler.
 *
 * If you are never going to use "graphics" (especially if you are not
 * compiling support for graphics anyway) then you can delete the "pict"
 * resources with id "1001", "1002", "1003" and "1004" with no dangerous
 * side effects.
 *
 *
 * This file assumes that you will be using a PPC Mac running OS X
 * or OS 8/9 (8.6 or greater) with CarbonLib system extention enabled.
 * In fact, the game will refuse to run unless these features are available.
 *
 * MACH_O_CARBON code pushes the system requirement a bit further, and
 * I don't think it works on System 8, even with CarbonLib, because it uses
 * the Bundle services, but I may be wrong.
 *
 * Note that the "preference" file is now a simple XML text file
 * called "<program name>.plist" in case of PEF Carbon, and "<Java-style
 * program id defined in Info.plist>.plist" for Mach-O Carbon, which contains
 * key-value paris, so it no longer has to check version stamp to validate
 * its contents.
 *
 *
 * Note that "init1.c", "init2.c", "load1.c", "load2.c", and "birth.c"
 * should probably be "unloaded" as soon as they are no longer needed,
 * to save space, but I do not know how to do this.  XXX XXX XXX
 *
 * Stange bug -- The first "ClipRect()" call crashes if the user closes
 * all the windows, switches to another application, switches back, and
 * re-opens the main window, for example, using "command-a".  XXX XXX XXX
 *
 *
 * Initial framework (and most code) by Ben Harrison (benh@phial.com).
 *
 * Some code adapted from "MacAngband 2.6.1" by Keith Randall
 *
 * Initial PowerMac port by Maarten Hazewinkel (mmhazewi@cs.ruu.nl).
 *
 * Most Apple Event code provided by Steve Linberg (slinberg@crocker.com).
 *
 * Most of the graphics code is adapted from an extremely minimal subset of
 * the "Sprite World II" package, an amazing (and free) animation package.
 *
 * Carbon code adapted from works by Peter Ammon and Ron Anderson.
 *
 * (List of changes made by "pelpel" follow)
 * Some API calls are updated to OS 8.x-- ones.
 *
 * Pixmap locking code in Term_pict_map() follows Carbon Porting Guide
 * by Apple.
 *
 * The idle loop in TERM_XTRA_DELAY is rewritten to sleep on WaitNextEvent
 * for a couple of reasons.
 *
 * CheckEvent now really blocks whenever asked to wait.
 *
 * The unused buffer GWorld is completely removed. It has long been pure waste
 * of memory.
 *
 * The default font-size combination was changed because the old one, Monaco
 * at 12 points causes the redraw artefact problem on OS X.
 *
 * Characters in the ASCII mode are clipped by their bounding rects to reduce
 * redraw artefacts that were quite annoying in certain font-point combos.
 *
 * Transparency effect now avoids double bitblts whenever possible.
 *
 * Old tiles were drawn in a wrong fashion by the USE_TRANSPARENCY code.
 *
 * ASCII and the two graphics modes are now controlled by single graf_mode
 * variable.  arg_* and use_* variables are set when requested mode is
 * successfully initialised.
 *
 * Most of the menus are now loaded from resources.
 *
 * Moved TileWidth and TileHeight menus into Special. There were too many menus.
 *
 * Added support for 32x32 tiles, now for [V] only.
 *
 * Related to the above, globe_init no longer loads tile images twice if
 * a tileset doesn't have corresponding masks.
 *
 * Added support for POSIX-style pathnames, for Mach-O Carbon (gcc, CW >= 7).
 * We can finally live without Pascal strings to handle files this way.
 *
 * (Mach-O Carbon) Graphics tiles are moved out of the resource fork into
 * bundle-based data fork files.
 *
 * Changed size-related menu code, because they no longer function because
 * some APIs have been changed to return Unicode in some cases.
 *
 * Changed the transparency code again, this time using Ron Anderson's code,
 * which makes more sound assumption about background colour and is more
 * efficient.
 *
 * The old asynchronous sound player could try to lock the same handle more
 * than once, load same sound resource already in use, or unlock and release
 * currently playing sound.
 *
 * hook_quit() now releases memory-related resources dynamically allocated by
 * the graphics and sound code.
 *
 * Important Resources in the resource file:
 *
 *   FREF 130 = ANGBAND_CREATOR / 'APPL' (application)
 *   FREF 129 = ANGBAND_CREATOR / 'SAVE' (save file)
 *   FREF 130 = ANGBAND_CREATOR / 'TEXT' (generic text file)
 *   FREF 131 = ANGBAND_CREATOR / 'DATA' (binary image file, score file)
 *
 *   DLOG 128 = "About Angband..."
 *
 *   ALRT 128 = unused (?)
 *   ALRT 129 = "Warning..."
 *
 *   DITL 128 = body for DLOG 128
 *   DITL 129 = body for ALRT 129
 *   DITL 130 = body for ALRT 130
 *
 *   ICON 128 = "warning" icon
 *
 *   MBAR 128 = array of MENU id's (128, 129, 130, 131, 132, 133, 134)
 *   MENU 128 = apple (about, -, ...)
 *   MENU 129 = File (new, open, close, save, -, score, quit)
 *     (If SAVEFILE_SCREEN is defined)
 *   MENU 129 = File (close, save, -, score, quit)
 *   MENU 130 = Edit (undo, -, cut, copy, paste, clear)
 *   MENU 131 = Font (bold, wide, -)
 *   MENU 132 = Size ()
 *   MENU 133 = Windows ()
 *   MENU 134 = Special (Sound, Graphics, TileWidth, TileHeight, -, Fiddle,
 *                       Wizard)
 *              Graphics have following submenu attached:
 *   MENU 144 = Graphics (None, 8x8, 16x16, 32x32, enlarge tiles)
 *              TileWidth and TileHeight submenus are filled in by this program.
 *   MENU 145 = TileWidth ()
 *   MENU 146 = TileHeight ()
 *
 *   On CFM(PEF) Carbon only:
 *   PICT 1001 = Graphics tile set (8x8)
 *   PICT 1002 = Graphics tile set (16x16 images)
 *   PICT 1004 = Graphics tile set (32x32)
 *
 *   Mach-O Carbon now uses data fork resources:
 *   8x8.png   = Graphics tile set (8x8)
 *   16x16.png = Graphics tile set (16x16 images)
 *   32x32.png = Graphics tile set (32x32)
 *   These files should go into the Resources subdirectory of an application
 *   bundle.
 *
 *   STR# 128 = "Please select the "lib" folder"
 *
 *   plst 0   can be empty, but required for single binary Carbon apps on OS X
 *            Isn't necessary for Mach-O Carbon.
 *
 *
 * File name patterns:
 *   all 'APEX' files have a filename of the form "*:apex:*" (?)
 *   all 'DATA' files have a filename of the form "*:data:*"
 *   all 'SAVE' files have a filename of the form "*:save:*"
 *   all 'USER' files have a filename of the form "*:user:*" (?)
 *
 * Perhaps we should attempt to set the "_ftype" flag inside this file,
 * to avoid nasty file type information being spread all through the
 * rest of the code.  (?)  This might require adding hooks into the
 * "fd_open()" and "my_fopen()" functions in "util.c".  XXX XXX XXX

/*
 * Yet another main-xxx.c for Carbon (pelpel) - revision 11d
 *
 * Since I'm using CodeWarrior, the traditional header files are
 * #include'd below.
 *
 * I also compiled Angband 3.0.2 successfully with OS X's gcc.
 * Please follow these instructions if you are interested.
 *
 * ---(developer CD gcc + makefile porting notes, for Angband 3.0.2)-------
 * 1. Compiling the binary
 *
 * If you try this on OS X + gcc, please use makefile.std, replacing
 * main.c and main.o with main-crb.c and main-crb.o, removing all main-xxx.c
 * and main-xxx.o from SRCS and OBJS, and, and use these settings:
 *
 * COPTS = -Wall -O1 -g -fpascal-strings
 * INCLUDES =
 * DEFINES = -DMACH_O_CARBON -DANGBAND30X
 * LIBS = -framework CoreFoundation -framework QuickTime -framework Carbon
 *
 * -DANGBAND30X only affects main-crb.c. This is because I'm also compiling
 * a couple of variants, and this arrangement makes my life easier.
 *
 * Never, ever #define MACINTOSH.  It'll wreck havoc in system interface
 * (mostly because of totally different pathname convention).
 *
 * You might wish to disable some SET_UID features for various reasons:
 * to have user folder within the lib folder, savefile names etc.
 *
 * For the best compatibility with the Classic ports and my PEF Carbon
 * ports, my_fopen, fd_make and fd_open [in util.c] should call
 *   (void)fsetfileinfo(buf, _fcreator, _ftype);
 * when a file is successfully opened.  Or you'll see odd icons for some files
 * in the lib folder.  In order to do so, extern.h should contain these lines,
 * within #ifdef MACH_O_CARBON:
 *   extern int fsetfileinfo(char *path, u32b fcreator, u32b ftype);
 *   extern u32b _fcreator;
 *   extern u32b _ftype;
 * And enable the four FILE_TYPE macros in h-config.h for defined(MACH_O_CARBON)
 * in addition to defined(MACINTOSH) && !defined(applec), i.e.
 *  #if defined(MACINTOSH) && !defined(applec) || defined(MACH_O_CARBON)
 *
 * This is a very good way to spot bugs in use of these macros, btw.
 *
 * 2. Installation
 *
 * The "angband" binary must be arranged this way for it to work:
 *
 * lib/ <- the lib folder
 * Angband (OS X).app/
 *   Contents/
 *     MacOS/
 *       angband <- the binary you've just compiled
 *     Info.plist <- to be explained below
 *     Resources/
 *       Angband.icns
 *       Data.icns
 *       Edit.icns
 *       Save.icns
 *       8x8.png <- 8x8 tiles
 *       16x16.png <- 16x16 tiles
 *       angband.rsrc <- see below
 *
 * 3. Preparing Info.plist
 *
 * Info.plist is an XML file describing some attributes of an application,
 * and this is appropriate for Angband:
 *
 * <?xml version="1.0" encoding="UTF-8"?>
 * <plist version="1.0">
 *   <dict>
 *     <key>CFBundleName</key><string>Angband</string>
 *     <key>CFBundleDisplayName</key><string>Angband (OS X)</string>
 *     <key>CFBundleExecutable</key><string>angband</string>
 *     <key>CFBundlePackageType</key><string>APPL</string>
 *     <key>CFBundleSignature</key><string>A271</string>
 *     <key>CFBundleVersion</key><string>3.0.2</string>
 *     <key>CFBundleShortVersionString</key><string>3.0.2</string>
 *     <key>CFBundleIconFile</key><string>Angband</string>
 *     <key>CFBundleIdentifier</key><string>net.thangorodrim.Angband</string>
 *     <key>CFBundleInfoDictionaryVersion</key><string>6.0</string>
 *     <key>CFBundleDocumentTypes</key>
 *       <array>
 *         <dict>
 *           <key>CFBundleTypeExtentions</key><array><string>*</string></array>
 *           <key>CFBundleTypeIconFile</key><string>Save</string>
 *           <key>CFBundleTypeName</key><string>Angband saved game</string>
 *           <key>CFBundleTypeOSTypes</key><array><string>SAVE</string></array>
 *           <key>CFBundleTypeRole</key><string>Editor</string>
 *         </dict>
 *         <dict>
 *           <key>CFBundleTypeExtentions</key><array><string>*</string></array>
 *           <key>CFBundleTypeIconFile</key><string>Edit</string>
 *           <key>CFBundleTypeName</key><string>Angband game data</string>
 *           <key>CFBundleTypeOSTypes</key><array><string>TEXT</string></array>
 *           <key>CFBundleTypeRole</key><string>Editor</string>
 *         </dict>
 *         <dict>
 *           <key>CFBundleTypeExtentions</key><array><string>raw</string></array>
 *           <key>CFBundleTypeIconFile</key><string>Data</string>
 *           <key>CFBundleTypeName</key><string>Angband game data</string>
 *           <key>CFBundleTypeOSTypes</key><array><string>DATA</string></array>
 *           <key>CFBundleTypeRole</key><string>Editor</string>
 *         </dict>
 * 	</array>
 *   </dict>
 * </plist>
 *
 * 4. Menu, diaglogue and gfx resources
 *
 * The binary assumes angband.rsrc should be in the traditional resource
 * mangager format.  Please run this command to create it from its textual
 * description:
 *
 * Rez -i /Developer/Headers/FlatCarbon -d MACH_O -o angband.rsrc Angband.r
 *
 * The command is in /Developer/Tools.  You might wish to include it in your
 * PATH.
 *
 * It's better to comment out the definitions of BNDL and plst resources
 * before you do that.  I think you can DeRez the resulting tome.rsrc and
 * feed it to the Interface Builder to produce a set of compatible .nib files,
 * but this file also needs to be updated to understand .nib...  On the other
 * hand, I really don't like to hardcode UI definitions in C.
 *
 * Graphics resources are moved out of the resource fork and become ordinary
 * PNG files.  Make sure to set its resolution to 72 dpi (<- VERY important)
 * while keeping vertical and horizontal scaling factor to 100% (<- VERY
 * important), when you convert tiles in any formats to PNG.  This means
 * that the real size of an image must shrink or grow when you change it's dpi.
 *
 * Sound resources are a bit more complicated.
 * The easiest way is:
 * 1) Grab recent Mac Angband binary.
 * 2) Run this command:
 *   DeRez -only 'snd ' (Angband binary) > sound.r
 * 3) And specify sound.r files in addition to Angband.r when you run Rez.
 *
 * ---(end of OS X + gcc porting note)--------------------------------------
 *
 * Code adapted from Peter Ammon's work on 2.8.3 and some modifications
 * are made when Apple's Carbon Porting Guide says they are absolutely
 * necessary. Other arbirary changes are mostly because of my hatred
 * of deep nestings and indentations. The code for controlling graphics modes
 * have been thoroughly revised simply because I didn't like it (^ ^;).
 * A bonus of this is that graphics settings can be loaded from Preferences
 * quite easily.
 *
 * I also took Ron Anderson's (minimising the use of local-global coordinate
 * conversions). Some might say his QuickTime multimedia is the most
 * significant achievement... Play your favourite CD instead, if you really
 * miss that (^ ^;) I might consider incorporating it if it makes use of
 * event notification.
 *
 * I replaced some old API calls with new (OS 8.x--) ones, especially
 * when I felt Apple is strongly against their continued usage.
 *
 * Similarly, USE_SFL_CODE should be always active, so I removed ifdef's
 * just to prevent accidents, as well as to make the code a bit cleaner.
 *
 * On the contrary, I deliberately left traditional resource interfaces.
 * Whatever Apple might say, I abhor file name extentions. And keeping two
 * different sets of resources for Classic and Carbon is just too much for
 * a personal project XXX
 *
 * Because Carbon forbids the use of 68K code, ANGBAND_LITE_MAC sections
 * are removed.
 *
 * Because the default font-size combination causes redraw artefact problem
 * (some characters, even in monospace fonts, have negative left bearings),
 * I introduced rather crude hack to clip all character drawings within
 * their bounding rects. If you don't like this, please comment out the line
 * #define CLIP_HACK
 * below.
 *
 * The check for return values of AEProcessAppleEvent is removed,
 * because it results in annoying dialogues on OS X, also because
 * Apple says it isn't usually necessary.
 *
 * Because the always_pict code is *so* slow, I changed the graphics
 * mode selection a bit to use higher_pict when a user chooses a fixed
 * width font and doesn't changes tile width / height.
 *
 * Added support for David Gervais' 32x32 tiles.
 *
 * Replaced transparency effect code by Ron Anderson's.
 *
 * Added support for gcc & make compilation. They come free with OS X
 * (on the developer CD).  This means that it can be compiled as a bundle.
 *
 * For Mach-O Carbon binary, moved graphics tiles out of the
 * resource fork and made them plain PNG files, to be stored in the application
 * bundle's "Resources" subdirectory.
 *
 * For Mach-O Carbon binary, provided a compile-time option (USE_QT_SOUND) to
 * move sound effect samples out of the resource fork and use *.wav files in
 * the bundle's "Resources" subdirectory. The "*" part must match the names in
 * angband_sound_name (variable.c) exactly. This doesn't hurt performance
 * a lot in [V] (it's got ~25 sound events), but problematic in [Z]-based
 * ones (they have somewhere around 70 sound events).
 *
 * You still can use the resource file that comes with the ext-mac archive
 * on the Angband FTP server, with these additions:
 * - MENUs 131--134 and 144--146, as described above
 * - MBAR 128: just a array of 128 through 134
 * - plst 0 : can be empty, although Apple recommends us to fill it in.
 * - STR# 128 : something like "Please select your lib folder"
 *
 * Since this involves considerable amount of work, I attached
 * a plain text resource definition (= Rez format) .
 * I heavily commented on the file, hoping it could be easily adapted
 * to future versions of Angband as well as variants.
 * I omitted sound effects and graphic tiles to make it reasonably small.
 * Please copy them from any recent Mac binaries - you can use, say ZAngband
 * ones for Vanilla or [V]-based variants quite safely. T.o.M.E. uses fairly
 * extended 16x16 tileset and it is maintained actively. IIRC Thangorodrim
 * compile page has an intruction explaining how to convert tiles for
 * use on the Mac... It can be tricky, depending on your choice of
 * graphics utility. Remember setting resolution to 72 pixels per inch,
 * while keeping vertical/horizontal scale factor to 100% and dump the
 * result as a PICT from resource.
 *
 * To build Carbonised Angband with CodeWarrior, copy your PPC project
 * and
 * - replace main-mac.c in the project with this file (in the link order tab)
 * - remove InterfaceLib and MathLib
 * - add CarbonLib (found in Carbon SDK or CW's UniversalInterfaces) --
 *   if you have compiler/linker errors, you'll need Carbon SDK 1.1 or greater
 * - replace MSL C.PPC.Lib with MSL C.Carbon.Lib (both found in
 *   MSL:MSL_C:MSL_MacOS:Lib:PPC)
 * - leave MSL RuntimePPC.Lib as it is
 * - don't forget to update resource file, as described above
 * - as in Classic targets, you may have to include <unistd.h> and
 *   <fcntl.h>. The most convinient place for them is the first
 *   #ifdef MACINTOSH in h-system.h
 * - check variant dependent ifdef's explained below, and add
 *   appropriate one(s) in your A-mac-h.pch.
