- fixed the use of Doom-Legacy-style 3D floor lighting in light mode 8.

Browse source 
Legacy used some strange blending formula to calculate its colormaps for colored 3D floor lighting, this is not available in the software lighting mode, so for these the engine has to temporarily revert to light mode 2 to render them correctly.
