/*===========================================================
STRATEGY FOR OPENGL CONTEXT CREATION
- If the requested level of anti-aliasing is not supported and is greater than 2, try with 2
--> if level 2 fails, disable anti-aliasing
--> it's important not to generate an error if anti-aliasing is not supported
- Use a matching pixel mode, or the best of all available pixel modes if no perfect match ;
You should use the function EvaluateConfig to get a score for a given configuration
- Don't forget to fill Params (see constructors) back with the actual parameters we got from the chosen pixel format
- IMPORTANT : all OpenGL contexts must be shared (usually a call to xxxShareLists)
===========================================================*/
/*===========================================================
STRATEGY FOR EVENT HANDLING
- Process any event matching with the ones in sf::Event::EventType
--> Create a sf::Event, fill the members corresponding to the event type
--> No need to handle joystick events, they are handled by WindowImpl::ProcessJoystickEvents
--> Event::TextEntered must provide UTF-16 characters
(see http://www.unicode.org/Public/PROGRAMS/CVTUTF/ for unicode conversions)
--> Don't forget to process any destroy-like event (ie. when the window is destroyed externally)
- Use SendEvent function from base class to propagate the created events
