- made bloom and tonemap settings game specific and save all related CVARs.
...
As was pointed out: "That said, there is one minor problem - different game artstyles can constitute whether Bloom is turned on, which tonemap is used, etc. For example, when playing Doom, I like having my bloom on, but if I am going to start playing the Adventures of Square, the art style and bloom don't mix, in my opinion. For this, I have to remember to switch my bloom settings every time I switch IWad"

...
This was done to clean up the license and to ensure that any commercial fork of the engine has to obey the far stricter requirements concerning source distribution. The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.

This replaces the in-place application of fullscreen colormaps if renderbuffers are active. This way the fully composed scene gets inverted, not each element on its own which is highly problematic for additively blended things.

This fixes invisible player sprites in recursive line portals.

- adjustments for weapon rendering in GL.
...
This adds support for the new weapon state code and fixed some lighting calculations.
Note that this currently will not allow combination of HUD models with other sprite frames yet.

- cleaned up the clip plane management for portals.
...
Unfortunately the math behind the old clip planes is utterly impenetrable and so poorly documented that I have no idea how to set that up, so it is deactivated for now. It wasn't working anyway.
