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