#15 Touch Screens won't work under DGA 2.0

[Dean L. Hedin]

OS - Mandrake 7.1
Latest allegro from CVS

I have both Microtouch and ELO graphic touchscreens working
OK on the KDE desktop. When I run exmouse in GFX_DGA2 and
use the mouse it's OK also. The touchscreens will not work.

I have modified xdga2.c to incorportate the "some DGA servers are buggy" as found in the old DGA1 code.

This improves the situation, however coords are way off
and it seems to be running in relative mode with y axis inversed.

This may be an issue in DGA2 itself. Presently looking for
non-allegro DGA app to isolated problem.

Update - This is a problem with DGA. Xfree86 only suports
relative mouse events. You must modify Xfree sources
(specifically the DGA event handling) to "pass through"
mouse events without converting them to relative coordinates. Some modification to allegro mouse handling is also required (for the DGA case)
