GL_EXT_framebuffer_object changes
---------------------------------
-XXX describe all the changes made for this extension.
+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.
