Hi,

before you get too far in this clipping thing I would like to remind you 
about the Lynx needs.

The Lynx has a much larger drawing area and only a small viewport. 
Usually the scene is drawn at 512 by 512 pixels and the viewport (160 by 
102 pixels) is following the game character and scrolled around the game 
area. All "clipping" is done in hardware. There is no need for any kind 
of software clipping.

I have not checked the tgi driver for this yet. But it should be 
possible to draw on any screen coordinates. Also outside the visible 
screen area. If the tgi driver limits this then I probably need to 
create another driver for 512 by 512 pixel screens that could be used 
for platformers. (And also a new tgi_setviewport call for moving the 
visible screen around the playfield.)

Karri
