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.

9c99cf29db Have OpenGL2 "map $lightmap" check for NULL tr.lightmaps too 
Zero length lightmap lump will have NULL tr.lightmaps.

OpenGL1 already has this check, because r_vertexLight 1
would crash Team Arena. OpenGL2 does not disable loading lightmaps
when r_vertexLight is 1 though, so it does not have that issue.

c8c7bb1dc3 Fix R_GetEntityToken ending prematurely 
If spawn var key or value is "" it caused R_GetEntityToken (available to
cgame, used by opengl2) to stop parsing, whereas game VM would continue.

Changed it to match parsing used for game VM
(see G_GET_ENTITY_TOKEN in code/server/sv_game.c).

The map poq3dm5 has a "wait" key with value "".

e7f43545ed Don't wash out HDR vertex lite surfaces in OpenGL2 
Vertex lite surfaces being brighter than light maps looks bad,
they're meant to look the same. Especially in ET, which mixes
them fequently. It's noticeable in Q3 too though.

BSP lightmaps (i.e. not external HDR lightmaps) use
R_ColorShiftLightingBytes, now *Floats (used by vertex colors)
has the same behavior.

This may be a problem for HDR lightmaps, as the RGB will always be
scaled to 0.0 to 1.0 range.

I had enabled this for non-HDR before, but now HDR needs it too.

dde36d91ce Fix OpenGL2 non-HDR map surface over brighting 
Vertex lit map surfaces were saturating to white when
r_mapOverBrightBits was increased and r_hdr was disabled.

Now the color is normalized like lightmaps and lightgrid
when r_hdr is disabled. Which is the same as OpenGL1.

Noticeable on misc_model trisoup.

973a616061 Fix white flash levelshot bug in OpenGL1 
If you tried to draw the last loaded image, gl texture 0 (which is appearently white)
was used because renderer thought the image was already bound.

Why OpenGL1 renderer binds texture 0, I have no idea. It's been removed from OpenGL2.
