No, you aren't missing much :-)
I'm (slowly) going on with dib engine, I choose at first Jesse's one as 
starting point because it had a source file structure I liked more.
Now I'm merging Huw's one, it has ROP support, pen and brushes.... 
Stuffs are going on. I paused the font code for a while, it's very basic 
by now but I wanted to see "something" in order to test the speed 
difference in autocad.... which is awesome.
The engine still have some bugs that cause it crashing sometimes... I'm 
investigating about it before going on.
When I'll get something stable I'll post the code somewhere.
About disabling/enabling the engine, there are 4 choices :
1-by registry
2-by environment variable
3-by ./configure
4-simply removing; driver goes thru x11 if it doesn't exist.
