Drawing the negative layer last is not correct, since it erases
everything below the negative objects in all layers. The attached
patch seems to do the trick right. All layers (=layers as they are
seen in gerbview, not individual layers in a gerber file) are first
drawn into a bitmap and negative objects are drawn in background
color. Then the bitmap itself is used as a mask in blitting the bitmap
onto the screen.
