Oh, and something else:

* Instead of fillRect(x,y,w,h, black, transparent) you can do 
eraseRect(x,y,w,h)

* And are you sure you don't want to create the temporary layer with the 
composite op and the transparency value of the paint tool? I.e, the composite 
op/transparency done to show what's going on shouldn't that be the same comp. 
op/transp. you're going to flatten this layer onto the target layer with?
