Subject: Fix and enable GL_MESA_ycbcr_texture.  Looks fine with yuvrect.  I'm slightly
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f33beed330c22b56bb97af73f56d83c34e985cb6;p=mesa.git

Fix and enable GL_MESA_ycbcr_texture.  Looks fine with yuvrect.  I'm slightly
concerned that TEXEL_YUV422 looks like TEXEL_YVU422 and TEXEL_VUY422 looks like
TEXEL_VYU422 in yuvrect, but I'm happy enough for now.
