Add a lot of debug/experimental options

[f1refa11]

• GL_ACCELERATED_VISUAL attribute: "Set to 1 to require hardware acceleration, or 0 to force software render. By default, both are allowed."
• GL_MULTISAMPLEBUFFERS and GL_MULTISAMPLESAMPLES attributes, which enables multisampling anti-aliasing
• "Try to update only certain parts of the window"
• "Use GPU-acceleration features" option which will try to use the latest pygame-ce(and maybe 3rd party libraries) features for using GPU for rendering

ill add other later
