- make the warp2 shader's formula match the software renderer's.
...
This fixes some jerkiness with vertical scrollers due to a bad sine period and makes the overall appearance of the effect what it was originally supposed to be. The old warp2 shader was not created by replicating the formula but by trial and error until it looked close enough.
A version of the old warp2 shader with a fixed sine period is still available as a custom hardware shader.

...
* disable the dynamic light code if no buffers are available
* added a duplicate of the getTexel function which cannot be patched without creating syntax problems.
* fixe int<->float conversion warning, which on some compilers may be an error.

- fixed: Even though the name REDISALPHA implies otherwise, this render mode still needs to respect a texture's alpha channel to ensure that things get rendered properly. Otherwise the SmoothEdges function cannot be used which is necessary to ensure that filtered textures look correct.

- fixed: When changing enhanced nightvision mode the shaders need to have their fixed colormap state reset to ensure that the new settings get used.

- fixed: The shader code for handling special fixed colormaps did not use the color vertex attribute which was most evident with the 'shadow' render style on the spectre.

- changed the handling of alpha textures. The only special case they need is with palette-less textures and this can be handled far more easily and robustly with a predefined translation instead of passing another parameter through all the layers of the texture management code. This also fixes problems with paletted PNGs that get used as an alpha texture because the old method clobbered the image's palette.

- decided to restrict the 2.0 beta to OpenGL 4.x with GL_ARB_buffer_storage extension and removed all code for supporting older versions.
...
Sadly, anything else makes no sense.
All the recently made changes live or die, depending on this extension's presence.
Without it, there are major performance issues with the buffer uploads. All of the traditional buffer upload methods are without exception horrendously slow, especially in the context of a Doom engine where frequent small updates are required.
It could be solved with a complete restructuring of the engine, of course, but that's hardly worth the effort, considering it's only for legacy hardware whose market share will inevitably shrink considerably over the next years.
And even then, under the best circumstances I'd still get the same performance as the old immediate mode renderer in GZDoom 1.x and still couldn't implement the additions I'd like to make.
So, since I need to keep GZDoom 1.x around anyway for older GL 2.x hardware, it may as well serve for 3.x hardware, too. It's certainly less work than constantly trying to find workarounds for the older hardware's limitations that cost more time than working on future-proofing the engine.
This new, trimmed down 4.x renderer runs on a core profile configuration and uses persistently mapped buffers for nearly everything that is getting transferred to the GPU. (The global uniforms are still being used as such but they'll be phased out after the first beta release.

- removed the code for hardware alpha testing again because it didn't work anymore with how things are set up now.
...
- we need to check all GL versions when trying to get a context because some drivers only give us the version we request, leaving out newer features that are not exposed via extension.
- added some status info about uniform blocks.

- reactivate compatibility profile so that immediate mode drawing can be used on older hardware not supporting persistently mapped buffers.
...
- reactivate alpha testing per fixed function pipeline
- use the 'modern' way to define clip planes (GL_CLIP_DISTANCE). This is far more portable than the old glClipPlane method and a lot more robust than checking this in the fragment shader.
