Subject: mesa: initialize ctx->Stencil._BackFace = 1
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2a968113a925845331f0532a5a20d9fa1502c118;p=mesa.git

mesa: initialize ctx->Stencil._BackFace = 1

Back-face stencil operations didn't work correctly because this value was
zero.  It needs to be 1 or 2.  The only place it's set otherwise is in
glEnable/Disable(GL_STENCIL_TEST_TWO_SIDE_EXT).
