145 /* The value of "color_ordering" is somewhat arbitrary. It incorporates some
146 observations of the behavior of Windows systems, but also subjective judgments
147 about what color formats are more "normal" than others.
148
149 On at least some Windows systems, integer color formats are listed before
150 floating-point formats. Within the integer formats, higher color bits were
151 usually listed before lower color bits, while for floating-point formats it
152 was the reverse. However, that leads D3D to select 64-bit integer formats in
153 preference to 32-bit formats when the latter would be sufficient. It seems
154 that a 32-bit format is much more likely to be normally used in that case.
155
156 Also, there are certain odd color formats supported on the Mac which seem like
157 they would be less appropriate than more common ones. For instance, the color
158 formats with alpha in a separate byte (e.g. kCGLRGB888A8Bit with R8G8B8 in one
159 32-bit value and A8 in a separate 8-bit value) and the formats with 10-bit RGB
160 components.
161
162 For two color formats which differ only in whether or not they have alpha bits,
163 we use the same ordering. pixel_format_comparator() gives alpha bits a
164 different weight than color formats.
