Subject: mesa: Fix detection of whether an ARB_vp is enabled for two sided lighting.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c0cd9471173cd2287d74f5a536577348c789da5d;p=mesa.git

mesa: Fix detection of whether an ARB_vp is enabled for two sided lighting.

When there is no ARB_vertex_program program enabled, the Current
pointer points at a default program, so we were always using
VERTEX_PROGRAM_TWO_SIDE, even for fixed function lighting.

Fixes piglit two-sided-lighting*
