DX11 plugin: Do destination-alpha in a single pass. No more drawing the same geometry twice! SMG is faster now because it uses destination-alpha extensively. This uses dual-source color blending, a DirectX 10-level feature. The equivalent OpenGL function comes from the GL_ARB_blend_func_extended extension, which was made core in OpenGL 3.3.
