To fully support the erasure in a multi layer display, don't we also 
have to:


1) draw the tracks in the order of occurrence within the gerber file? 
Our track->Insert() logic may be inserting these tracks backwards. This 
is not hard to fix.


2) buffer each whole layer in its own separate bitmap while drawing, and 
then OR the bit map into the display. Otherwise the erasure will erase 
stuff from other layers.


More food for thought.
