Subject: Get the default GLXPixmap texture target from the server when appropriate.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=23635510e3333ea8056311afa741c5e6d7c9ec15;p=mesa.git

Get the default GLXPixmap texture target from the server when appropriate.

Fixes compiz with direct rendering when both GLX_TEXTURE_2D_EXT and
GLX_TEXTURE_RECTANGLE_EXT are supported for a GLXPixmap and the
application didn't specify the texture target as a GLX drawable attribute
when creating the GLX drawable.
