Modulate row interleaved stereo 3d offset with window height parity, because gl_FragCoord.y approaches zero at the bottom, not the top of the window.

Changes to the contrast/brightness/gamma formula for both hardware and shader gamma correction. Mainly makes a correction with the shader version where contrast/brightness being negative values would clip them inappropriately.

- draw the colormap blend after postprocessing, not before it.
...
- added colormap shader to postprocessing.
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.

- use static buffer data and a uniform to handle the texture positioning of the present shader.
...
That's again one less write access to the buffer. The uniform method was chosen because this way a buffer update can be completely avoided, and setting a single uniform is a lot cheaper and simpler to handle.

- 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.

- added clip planes for line portals and mirrors. This should eliminate the remaining problems with some visible geometry in front of the portal, it is also necessary to handle sprite splitting across line portals properly.

- made some changes to the shaders to allow downpatching them to GLSL 1.2:
...
* 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.

- removed the 'layout' qualifier from the uniform buffer declaration. It's not really needed because the layout of a single vec4 array cannot possibly change, and Intel drivers are complaining for unknown reasons.
