[Mesa-dev] [PATCH] i965: handle stencil_bits parameter for MESA_FORMAT_B8G8R8X8_UNORM format.

[Dawid Gan]

This format has been added in commit:
28090b30dd6b5977de085f48c620574214b6b4ba
But it was handled in the same way as MESA_FORMAT_B8G8R8A8_UNORM format.
It was causing the screen in Supertuxkart to be darker than expected, see:
