-/* Provide additional functionality on top of bufmgr buffers:
- * - 2d semantics and blit operations
- * - refcounting of buffers for multiple images in a buffer.
- * - refcounting of buffer mappings.
- * - some logic for moving the buffers to the best memory pools for
- * given operations.
- *
- * Most of this is to make it easier to implement the fixed-layout
- * mipmap tree required by intel hardware in the face of GL's
- * programming interface where each image can be specifed in random
- * order and it isn't clear what layout the tree should have until the
- * last moment.
