mesa: Add _mesa_format_fallback_rgbx_to_rgba() [v2]
The new function takes a mesa_format and, if the format is an alpha
format with a non-alpha variant, returns the non-alpha format.
Otherwise, it returns the original format.
Example:
input -> output
// Fallback exists
MESA_FORMAT_R8G8B8X8_UNORM -> MESA_FORMAT_R8G8B8A8_UNORM
MESA_FORMAT_RGBX_UNORM16 -> MESA_FORMAT_RGBA_UNORM16
// No fallback
MESA_FORMAT_R8G8B8A8_UNORM -> MESA_FORMAT_R8G8B8A8_UNORM
MESA_FORMAT_Z_FLOAT32 -> MESA_FORMAT_Z_FLOAT32
i965 will use this for EGLImages and DRIimages.
v2 (Jason Ekstrand):
- Use mako
- Rework to be easier to read
- Write directly to the output file
