SH-2084 Don't error out on framebuffer mismatch -- probably causing a crash when some post-snapshot or minimize/restore operation gets out of phase.

SH-2447, SH-2525, SH-2276 Strip out defunct global illumination code, add accounting for how much memory is taken up by LLRenderTarget, fix crash on login in bindGLIndices (work around driver bug that doesn't respect VAO state WRT to index buffers), remove some unused render targets, remove some unused shaders, make it possible to run a fullscreen session

SH-2276 Fix for failed assertions reported from debug-enabled viewers.  Also, remove "Basic Shaders" as a user settable option (shaders are always on if GL version >= 2.0, always off otherwise)

SH-2244 Don't use multisample texture (ever), and don't use GL_DEPTH_COMPONENT32 (use GL_DEPTH_COMPONENT24)

SH-469 Don't use depth buffers and multisample buffers where not absolutely needed -- make sample counts consistent between shaders and render targets.

* Fixed ATI mac "lighting and shadows" related crash
* Fixed up numerous GL errors on macs related to multiple color formats,
  the use of glEnable/glDisable on textures above the texture unit count
  and old ATI-specific code that was not appropriate for Mac.
* Disabled SSAO for ATI macs due to it not working with shadows
* Ongoing work to properly get shadows and SSAO functioning on ATI macs is required.

SH-373 Update glext.h, disable anti-aliasing on ATI when rendering deferred.  Get rid of RenderUseFBO debug setting (only use FBO when rendering deferred).  Use GL_ARB_framebuffer_objects instead of GL_EXT_...

More aggressive management of FBOs.  Allocate as few FBOs as possible, assert when FBOs are destroyed out of order.

Fix bad triangle in prim caps.
