It seems to me that the resource management code is the most blurry.
Also some of my notes about fastfill are wrong, removing them too.
* 2) ZB_DEPTHCLEARVALUE is used to clear a zbuffer and Z Mask must be
* equal to 0.
*
- * 3) RB3D_COLOR_CLEAR_VALUE is used to clear a colorbuffer and
- * RB3D_COLOR_CHANNEL_MASK must be equal to 0.
- *
- * 4) ZB_CB_CLEAR can be used to make the ZB units help in clearing
- * the colorbuffer. The color clear value is supplied through both
- * RB3D_COLOR_CLEAR_VALUE and ZB_DEPTHCLEARVALUE, and the colorbuffer
- * must be set in ZB_DEPTHOFFSET and ZB_DEPTHPITCH in addition to
- * RB3D_COLOROFFSET and RB3D_COLORPITCH. It's obvious that the zbuffer
- * will not be cleared and multiple render targets cannot be cleared
- * this way either.
- *
- * 5) For 16-bit integer buffering, compression causes a hung with one or
+ * 3) For 16-bit integer buffering, compression causes a hung with one or
* two samples and should not be used.

- * 6) Fastfill must not be used if reading of compressed Z data is disabled
+ * 4) Fastfill must not be used if reading of compressed Z data is disabled
* and writing of compressed Z data is enabled (RD/WR_COMP_ENABLE),
