SmSpillaz: so basically, compiz gets the cursor location
(17:19:01) SmSpillaz: and has special "Warp" areas on the screen
(17:19:06) SmSpillaz: so say with iScale
(17:19:43) SmSpillaz: If you move the cursor over a scaled window Y, redirect it to window Y's absolute position
(17:20:46) SmSpillaz: and scale the co-ordinates down in the scaled window and translate them to the window's actual position ( That the user cannot see or interact with normall - for obvious reasons)
(17:21:15) SmSpillaz: Then if the cursor goes in that "Region" It would just translate to where compiz tells it to go
(17:21:43) SmSpillaz: there would only be lag if the "Warp" areas were changeing quite often

Not quite too sure how it works with iZoom, but you get the point
