Fog rendering (including colored fog in maps in UDMF format).
Fixed lots of bugs in model loading and rendering.
Added "Toggle GZDoom Effects" button, which currently toggles dynamic lights, models and fog rendering.
Model loading process is more verbose now, so if something goes wrong, check Errors and Warnings window (F11) for details.
ColorPicker plugin:
You can now select surfaces in 3D-mode and then open Color Picker window to edit sector colors of sectors, to which these surfaces belong.
If nothing is selected, you can hilight a surface and then open Color Picker window to edit sector colors of sector, to which hilighted surface belongs.
If nothing is selected, you can hilight a Light Thing and then open Color Picker window to edit it's properties.
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).
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.
