I've just pushed a interface change to gallium.
A finer grained pipe_screen::is_format_supported was needed. Namely,
it needed to distinguish among different pipe_texture_targets, as
hardware some times has limitations in the formats that can be used
for cubemaps and texturemaps. The same thing goes for non-square
sizes, and non power of of two sizes.
And since I need to change the interface, I used this opportunity to
drop PIPE_SURFACE vs PIPE_TEXTURE outdated distinction, replacing it
by the tex_usage flags (PIPE_TEXTURE_USAGE_RENDER_TARGET and/or
PIPE_TEXTURE_USAGE_DISPLAY_TARGET).
In summary, this is how the new is_format_supported looks like:
/**
* Check if the given pipe_format is supported.
*
* \param tex_usage bitmask of PIPE_TEXTURE_USAGE_*
* \param flags a bitmask of PIPE_TEXTURE_GEOM_SQUARE and
* PIPE_TEXTURE_GEOM_NONPOWEROFTWO
*/
boolean (*is_format_supported)( struct pipe_screen *,
enum pipe_format format,
enum pipe_texture_target target,
unsigned tex_usage,
unsigned geom_flags );
