CVS Update (gamma ramps)

I added lots of gamma improvements in the latest CVS snapshot:

Changes for Tue, Aug 29:
1.1.5: Re-added SDL_SetGamma() using SDL_SetGammaRamp()
1.1.5: Added gamma ramp support to the DGA video driver
1.1.5: Finished X11 DirectColor visual support for gamma ramps

Next, Iā€™m going to see if the DGA and X11 video drivers can be merged. :slight_smile:

See ya!
