Adds a new FBO type kStencil_MSFBOType that is selected whenever NV_framebuffer_mixed_samples extension is available. In this new FBO type a non-msaa color buffer is created with a multisampled stencil buffer attachment. Replaces numSamples() with separate numColorSamples and numStencilSamples methods in RenderTarget. In mixed samples mode non-MSAA codepaths are used to draw simple shapes, while NVPR-rendered paths and text are rendered with a multisampled stencil.
