directx gdk backend?

["Michael Lawrence" <lawremi iastate edu>]

Hi,

From what I have read, it sounds like Windows Vista has regressed from XP in that it no longer offers any hardware acceleration for GDI. Does this mean that GDK will perform more slowly on Vista compared to XP? The performance of GDK is already slow when drawing lots of graphics, mostly due to this bug: 
http://bugzilla.gnome.org/show_bug.cgi?id=51828, which apparently will never be fixed. Is there a reason why that won't be fixed? Is it a lot of work? Since MS is putting all of its efforts into DirectX now, would it make sense to move to that for drawing?

Thanks,
Michael
