The non-fully operational DIB engine issue aside (I believe Gav covered that).
I'm curious to know how you propose to hook the DIB engine in?.. I looked at
several methods (changing the DC function table, for example) - none of them
looked very appealing to us.
The other issue to be considered, is it neceesarilly incorrect to call it from
the driver? Ove tells me that in Windows drivers are responsible for calling
Windows' DIB engine. This is because a) its easier for the driver to know
whats going to be faster, b) when the driver doesn't implement something
itself it just passes it off to the DIB engine.
