OpenGL Renderer: Fix some longstanding graphical glitches related to running Edge Mark and Fog with MSAA.
- These graphical glitches are resolved only when running 3.2 Core Profile with the GL_ARB_sample_shading extension, available on all modern GPUs.
- Do some minor optimizations to the Edge Mark and Fog shaders.
- Also fix an FBO attachment bug in legacy OpenGL that was introduced in commit 8b5ac56.
