Subject: demos/shadowtex: Don't set TEXTURE_WRAP_T for 1D texture
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0918023c28775ef6126e9f695a976ff199cd9a13;p=mesa.git

demos/shadowtex: Don't set TEXTURE_WRAP_T for 1D texture

The operation doesn't really make sense. It triggered a bug in the r300 DRI
driver (and possibly other drivers that simulate 1D textures via 2D textures).
I've added an isolated test case for this bug to Piglit, so everybody wins.
