Can anyone tell me how the mouse deals with overscan? I am having some problems with my tablet driver and overscan. Basically, I cannot get the mouse pointer
to the edges of the screen. Should I scale the numbers so that they are outside
the system window parameters of 640 x 400? I read in the ROM kernal manuals
that GFXBase Library contains these numbers and references these whenever doing
mouse operations. It seems that the system clips the mouse to the window. A
question, in overscan, is the left side of the screen's x coordinate less than
zero? When the mouse is at " zero " in x, it is not fully to the left side of
the screen. I am using IECLASS_POINTERPOS to position the pointer with the
tablet. I guess I need to know how overscan works. Is there any documentation?
