cull type the previous shader used (which could result in the skybox
not being visible due to only drawing back faces). The sky cloud stages
set the cull type so they are not affected by previous cull type.

d06deb41c8 Don't set fog image border color 
GL1's R_CreateImage sets GL texture to 0 before it ends, so border color is not
applied to the fog image. GL_CLAMP is not used for fog image (in either renderer),
so it would presumably not be used even if applied to the fog image.

c621589157 Fix 6155: OpenGL2: some shader stages remains visible through fog volumes 
Fix CalcFog in generic_vp.glsl to fog fogged surfaces.
Now it's the same as CalcFog in fogpass_vp.glsl.

Fixes shaders that use adjustColorsForFog. Impact wallmarks, blood sprites, flame textures and so on.

f17f58705c Remove a numIboIndexes=0 that is not read from GL2 tr_bsp.c 
numIboIndexes is set to 0 inside the loop for each surface. Does not need to be set before loop.

75cce50a9c Don't load external GLSL files by default 
External GLSL should probably only be used for development testing,
not released products. The GLSL files are tied to the code, and the
code changes some what often.

Fixes using OpenArena 0.8.8 which has incompatible GLSL files in a pk3.

95b241b8ba OpenGL2 don't try to dlight surfaces that had all dlights culled 
In the renderers, dlightbits are never cleared from world surfaces.
The dlight image does not repeat, so if it draws on extra surfaces it's
not visible.

However if using a repeating image (tr.defaultImage instead of tr.dlightImage);

  * In OpenGL1 image is only drawn on surfaces close to dlight origin.
  * In OpenGL2 image is draw on surfaces clearly outside the dlight radius, including past non-dlighted surfaces.

It seems there was a similar issue with pshadowBits. So update surface
dlightBits even if 0, like already done for pshadowBits. This causes
only surfaces close to origin to be affected. (Though it is a little
farther than in OpenGL1.)

I have no idea why this isn't a problem in OpenGL1.
