I did some testing, for me the "brush op", "indirect painting", "composite 
over" combination works fine. What doesn't seem to work is the opacity settings 
though.
"brush op", "direct painting", "composite over" do work, and opactiy is taken 
into account

But "brush op", "direct painting", "composite erase" or "eraser op" doesn't 
work, they give the invert result. Which leads me to believe the "composite 
erase" op of the alpha colorspace is broken.

Actually it is, if you draw at opacity 50%.
