From 13ae06cf36f9d04c0a04cdc19196f400d7a8c642 Mon Sep 17 00:00:00 2001

Subject: Large update 	- Remove via duplicates of shared template files 
 - Update driver to work with current versions of the above 	- Rework dma
 accounting 	- Rework emitting to dma to use a consistent set of macros

The handling of cliprects in the driver is still pretty questionable.
