99c8ba1288 - use uAddColor instead of uObjectColor2 for the ending color of a special colormap range.
Unlike uObjectColor2, this is more global state. uObjectColor2 is part of gradient calculation which may later be offloaded to a secondary buffer which already resulted in only conditionally setting it, resulting in broken special colormap application for the software renderer.

f10ded756e - split shadowmap AABB tree into two parts. one for static and one for dynamic
- upload only the dynamic AABB subtree using glBufferSubData
- change internal raytracing stack limit from 16 to 32
- update shadowmap AABB tree after R_SetupFrame for proper frame interpolation

9622ca7517 Add additive color before applying object colors
Based on what I saw in this video (https://youtu.be/Yx1tflavea8), the 
additive colors are applied before the object colors

f2dcff4386 - more options for Doom 64 style gradients on walls:
* Colors can npw be defined per sidedef, not only per sector.
* Gradients can be selectively disabled or vertically flipped per wall tier.
* Gradients can be clamped to their respective tier, i.e top and bottom of the tier, not the front sector defines where it starts.

The per-wall colors are implemented for hardware and softpoly renderer only, but not for the classic software renderer, because its code is far too scattered to do this efficiently.

c8852b8fea - enabled the linear shadowmap filter.
Although this doesn't look as good as the PCF version it is a lot less calculation intensive and therefore more suitable for weaker hardware.
It also tends to bleed through walls a lot less.

bc1e659c7b Revert "- reworked fog uniforms to move the global fog mode setting to the viewpoint buffer."
This reverts commit 8b26b6dd1e.

This was causing problems with light mode 2 because some edge cases were no longer handled properly.

4937848123 - refactoring of fixed colormap stuff to have it better organized and to reduce the number of uniforms in the main shader.
This removes 3 uniforms, consisting of 9 floats. Those were merged into other values that never get used at the same time.
It also moves the costly setup of the fixed colormap out of the render state into the 2D processing code.
Since 3D forces use of render buffers now, it is no longer necessary to draw the entire scene with the colormap active, meaning it can be handled more efficiently.

612fb40f3a - don't use uniforms related to fixed colormaps for other things.
The fixed colormap is a per-scene global setting that normally does not need to change ever during rendering of a scene so it's easily shoved aside into a static uniform buffer.
Having to change this buffer for inconsequential stuff should be avoided, especially when there's other uniforms that are just as good to hold these values.

ad7aaa8f2a - specify fragment output locations in the shader source.
OpenGL has been supporting this since version 3.3 and Vulkan requires it so it's the way to go.
