Both types are already binary equal: both are enums using the same bit values, but from compiler's perspective they're still different types, so it's warning. > ../glamor/glamor_trapezoid.c:123:47: warning: implicit conversion from > enumeration type 'PictFormatShort' (aka 'enum _PictFormatShort') to different > enumeration type 'pixman_format_code_t' [-Wenum-conversion] > 123 | image = pixman_image_create_bits(picture->format, > | ~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~^~~~~~ > 1 warning generated. The PICT_* fields, values and macros are relics from pre-pixman days (pixman, historically, essentially is the PICT_* stuff moved out to separate library) This has been a practical way for doing the transition from the old internal PICT_* code to pixman. Now it's time to finish it all up and drop the extra glue layer. In order to make it smooth, and also providing backwards compatibility for drivers (until they all keep up), just aliasing the types and adding #define's for the enum values.

|
|
* For dynamic indexed visuals (GrayScale and PseudoColor), these control the
|
|
* selection of colors allocated for drawing to Pictures. The default
|
|
* policy depends on the size of the colormap:
|
|
*
|
|
* Size Default Policy
|
|
* ----------------------------
|
|
* < 64 PolicyMono
|
|
* < 256 PolicyGray
|
|
* 256 PolicyColor (only on PseudoColor)
|
|
*
|
|
* The actual allocation code lives in miindex.c, and so is
|
|
* austensibly server dependent, but that code does:
|
|
*
|
|
* PolicyMono Allocate no additional colors, use black and white
|
|
* PolicyGray Allocate 13 gray levels (11 cells used)
|
|
* PolicyColor Allocate a 4x4x4 cube and 13 gray levels (71 cells used)
|
|
* PolicyAll Allocate as big a cube as possible, fill with gray (all)
|
|
*
|
|
* Here's a picture to help understand how many colors are
|
|
* actually allocated (this is just the gray ramp):
|
|
*
|
|
* gray level
|
|
* all 0000 1555 2aaa 4000 5555 6aaa 8000 9555 aaaa bfff d555 eaaa ffff
|
|
* b/w 0000 ffff
|
|
* 4x4x4 5555 aaaa
|
|
* extra 1555 2aaa 4000 6aaa 8000 9555 bfff d555 eaaa
|
|
*
|
|
* The default colormap supplies two gray levels (black/white), the
|
|
* 4x4x4 cube allocates another two and nine more are allocated to fill
|
|
* in the 13 levels. When the 4x4x4 cube is not allocated, a total of
|
|
* 11 cells are allocated.
