Subject: i965/tex: Unify the TexImage and TexSubImage code
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7bd5931cc1e1102e0171ca70bd2d6bbad81f71dc;p=mesa.git

i965/tex: Unify the TexImage and TexSubImage code

It's nearly the same so there's no good reason why it can't be in a
common function.  The one difference is that _mesa_store_teximage
calls AllocTextureImageBuffer for us, while _mesa_store_texsubimage
doesn't, but we don't need that anyway - intelTexImage already does it.
