mesa: add MESA_FORMAT_RGBX8888 and MESA_FORMAT_RGBX8888_REV
MESA_FORMAT_RGBX8888_REV is one of the opaque pixel formats used on Android. Thanks to texture-from-pixmap, drivers may actually see texture images with this format on Android. MESA_FORMAT_RGBX8888 is added only for completeness. Reviewed-by: Brian Paul <[email protected]> [olv: Move the new formats after MESA_FORMAT_ARGB8888_REV in gl_format. I accidentally moved them to the wrong place when preparing the patch.]
