+Implementing this extension involved changing a lot of code (for the better).
 
+The gl_framebuffer object now a collection of gl_renderbuffer objects.
+Renderbuffers may store colors, stencil indices, or depth values.  The
+gl_framebuffer and gl_renderbuffer types are object-oriented in design.

+All the old RGB, color index, stencil and depth-related span functions for
+reading/writing pixels from/to buffers has changed.  Now, all pixels are
+read/written through a set of common renderbuffer functions (methods).
+
+Most device drivers have been updated for these changes, but some haven't.

+
+<li><b><em>DRI/accelerated</em></b> - The DRI hardware drivers (for ATI,

+See the <a href="http://dri.freedesktop.org/wiki/Building" target="_parent">
+DRI Building Instructions</a> for the steps to build the DRM modules.

+Next, in the <code>Mesa-x.y.z/configs/default</code> file, set the
+<code>DRM_SOURCE_PATH</code> variable to indicate where the DRM files
+are located.

- * 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.
