done with fragment programs nowadays.
- MESA_GLX_ALPHA_BITS env var for xlib driver
Changes:
- removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead)
+ - removed GL_SGIX/SGIS_pixel_texture extensions
Bug fixes:

-/*
- * How this works:
- * 1. We load the image into a 2D texture.
- * 2. We generate a sequence of RGB images in which the R component
- * is really the S texture coordinate and the G component is really
- * the T texture coordinate.
- * By warping the mapping from R to S and G to T we can get non-linear
- * distortions.
- * 3. Draw the warped image (a 2-D warping function) with pixel texgen
- * enabled.
- * 4. Loop over the warped images to animate.
- *
- * The pixel texgen extension can also be used to do color-space
- * conversions. For example, we could convert YCR to RGB with a
- * 3D texture map which takes YCR as the S,T,R texture coordinate and
- * returns RGB texel values.
- *
- * You can use this extension in (at least) two ways:
- * 1. glDrawPixels w/ color space conversion/warping
- * 2. glDrawPixels to spatially warp another image in texture memory
- *
- * We're basically using glDrawPixels to draw a texture coordinate image.
