Added (Windows only): Use multisampling to achieve fullscreen antialiasing if available. Added (All platforms): Take advantage of the relaxed non-power-of-two rule in OpenGL if available, on textures which do not require mipmaps (can be disabled from the command line with -notexnonpow2). This dramatically reduces blurring on the smaller graphics caused by us having to previously rescale them. Revised GL_CalcLuminance so that it can be used with other resources and not just sprites.
