[Mesa-dev] [PATCH 04/12] mesa/main: Add MESA_FORMAT_X8_Z24 to _mesa_choose_tex_format

[chad at chad-versace.us]

From: Chad Versace <chad.versace at intel.com>

Prefer MESA_FORMAT_X8_Z24 over MESA_FORMAT_S8_Z24 for textures with
internal format GL_DEPTH_COMPONENT*.

i965 needs MESA_FORMAT_X8_Z24 for HiZ.
