Added "Dynamic light size" slider, which matches GZDoom's "Light size" option.
Added "Dynamic light intensity" slider, which matches GZDoom's "Light intensity" option.
Fixed Vavoom light rendering (was rendered as additive light, light radius was twise smaller than in GZDoom)
Fixed bug in light rendering introduced in v1.03 (light radius was set to -1 when switching from 2D to 3D mode).
Increased dynamic lights rendering performance (currently I'm getting around 25 FPS in Spawn's MAP01 with 32 dynamic lights and rendering distance set to 3000, was getting 4-6 FPS in GZDoomBuilder 1.02).
Several fixes in animated lights rendering (secondary light radius can now be smaller than primary light radius, Pulse Light's maximum radius was rendered twise bigger than in GZDoom).
All dynamic light types are now rendered correctly.
Added Doom-style shading on walls (walls going from west to east are slightly darker than walls going from north to south)
Masked surfaces are now correctly lit by dynamic lights.
Fixed several bugs in models rendering.
