+/* ink definition:
+ * ink dots can be printed in various sizes
+ * one size is called level
+ * every level is represented by a bitcombination and a density
+ * the density ranges from 0 (no dot is printed) to 1.0 (maximum dot size)
+ *
+ * an ink is therefore defined by the number of bits used for the bitpattern (bitdepth) and the number of possible levels:
+ * a 1 bit ink can have 2 possible levels 0 and 1
+ * a 2 bit ink can have 2*2=4 possible levels with the bitpatterns 0,1,2 and 3
+ * a 3 bit ink can have 2*2*2=8 possible levels with the bitpatterns 0 to 7
+ * ...
+ * some inks use less levels than possible with the given bitdepth
+ * some inks use special compressions to store for example 5 3 level pixels in 1 byte
+ * naming:
+ * dotsizes are named dotsizes_xl where x is the number of levels (number of dotsizes + 1)
+ * inks are named canon_xb_yl_ink where x is the number of bits representing the y possible ink levels
+ * inks that contain special (compression) flags are named canon_xb_yl_c_ink
+ * order:
+ * dotsizes are ordered ascending by the number of dots
