DescriptionWhile the game itself runs well on Core profile now, all the debug stuff does not.
This includes text entity, various debug boxes/lines from the game, and horde of renderer cvars which show something.

Implemented ImmediateRendering helper class, which emulates old-style calls when :
  r8567 Added helper for drawing like in immediate mode with GL core profile.
  r8569 ImmediateRendering: support 2D texcoord, store color as 8-bit.
  r8574 Fixed bug in ImmediateRendering::glColor4ub (broke r_showVertexColor).
  r8576 Now ImmediateRendering can transfer vertex data to VBO in chunks.

It collects geometrical data inside, and sometimes draws all of it by creating a temporary VBO and uploading the data to it.
If r_immediateRenderingEmulate is 0, then emulation is disabled and deprecated GL calls are done directly.
Note that you cannot set it to 0 if Core profile is active.

This list of commits changes render tools to use the new helper class.
  r8566 Moved RB_ShowTrace and RB_DrawExpandedTriangles to tr_rendertools.cpp.
  r8568 Fixed a bunch of debug tools using ImmediateRendering.
  r8571 Fixed r_showLightCount and r_showShadowCount.
  r8572 testImage and testVideo commands work.
  r8576 Now ImmediateRendering can transfer vertex data to VBO in chunks.

The final commit is:
  r8577 Do not try to run the still-broken render tools on Core profile.
Here is the list of stuff which I did not manage to fix:
        //stgatilov: this one uses qglArrayElement to fetch vertices from VBO
        RB_ShowSilhouette();
        //stgatilov: these ones use qglDrawPixels to display FBO contents
        RB_ShowDepthBuffer();
        RB_ShowIntensity();
        RB_TestGamma();
        RB_TestGammaBias();
