I think you can get some version by browsing CVS tree on Allegro
project page on sourceforge (Allegro project -> CVS Repository ->
Browse CVS Repository). Or get a unidiff from your current version
to some older version, save it and apply to your working CVS tree.

There might be a problem, as DGA driver doesn't save offsets if
Allegro screen is centered inside real screen (offset_x, offset_y in
_xdga_private_create_screen). You should save these offsets and add
them to coordinates in accelerated functions.
