Subject: gallium: fix state tracker's stencil buffer test
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=026465b9b1aebab98b6d519b75fe96d0ca9f4f51;p=mesa.git

gallium: fix state tracker's stencil buffer test

Need to check ctx->DrawBuffer->Visual.stencilBits not ctx->Visual.stencilBits
because the later only applies to the window system buffers, not user-created
FBOs.

This, plus the previous commit, fixes progs/tests/fbotexture.c
