[Mesa-dev] Uploading PIPE_FORMAT_B8G8R8A8_UNORM to pixmap texture in PIPE_FORMAT_B8G8R8X8_UNORM

[José Fonseca]

Jerome,

Hmm. B8G8R8A8 -> B8G8R8X8 should be accepted by
util_is_format_compatible.

It looks like util_is_format_compatible arguments are swapped, ie., it
should be 

    assert(util_is_format_compatible(util_format_description(src->format), util_format_description(dst->format)));

instead of 

    assert(util_is_format_compatible(util_format_description(dst->format), util_format_description(src->format)));

Jose
