It doesn't support such accelerators, but there are several ways to
consider adding support.  One might hide the interface between the
existing /dev/bitblt etc. files, so all programs can use the accelerator
on that hardware.  One might add new interface files, /dev/graphics
for example, that interested programs could look for to see if the
device is available, falling to the old way if the open fails.
The important point is, if possible and reasonable, to make the
interface available via files so that remote programs can access
the graphical hardware.
