libgui|GL: Perform multisampling with renderbuffers
With OpenGL 2.1, the only way to render into a texture with multisampling is to use OpenGL extensions.
GLFramebuffer now supports specifying a sample count. If more than one sample is requested, a secondary target is created with multisampled renderbuffers. Copying the multisampled contents to the attached texture occurs automatically.
Todo: Debug Oculus Rift’s multisampled framebuffer (one side visible only).
