OpenGL debugging code

Description

I was trying to investigate some OpenGL error (1280) that I consistently get as logged warning over and over again. It probably has to do with the NVidia RTX 2000 controller on this computer.

So I enabled RenderDebugGLSession in the settings and start the viewer and then get into a crash right during logging in. Looking at that crash it is an LL_ERRS() in LLGLSLShader::disableTexture() that claims it is expecting a TT_CUBE_MAP while it found a TT_CUBE_MAP_ARRAY. So I change that LL_ERRS into an LL_WARNS and run again and the next crash occurs in LLGLState::checkStates() "ASSERT (dstRGB == GL_ONE_MINUS_SRC_ALPHA)".

Is glDebug even supposed to work or is that so out of date that it will simply crash in one place or the other anyways?

The changes in develop-linux correct many opengl debugging errors including the TT_CUBE_MAP_ARRAY assert.

I'm going to checkout that branch and do a test compile and run with it. ;-)
