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