 			Sets the number of MSAA samples to use (as a power of two). MSAA is used to reduce aliasing around the edges of polygons. A higher MSAA value results in smoother edges but can be significantly slower on some hardware. See also bilinear scaling 3d [member rendering/scaling_3d/mode] for supersampling, which provides higher quality but is much more expensive.
