/* This is a hack ontop of a hack. Warping surfaces like those generated
by R_EmitWaterPolys() don't have a lightmap. Original Quake II therefore
negated the global intensity on those surfaces, because otherwise they
would show up much too bright. When we implemented overbright bits this
hack modified the global GL state in an incompatible way. So implement
a new hack, based on overbright bits... Depending on the value set to
gl_overbrightbits the result is different:
0: Old behaviour.
1: No overbright bits on the global scene but correct lightning on
warping surfaces.
2: Overbright bits on the global scene but not on warping surfaces.
