MAINTAINERS: Updated my entry (it wasn't there ;)
app/paint_core.[ch] supplied new PaintTool states to clone_paint_func() so that
writes of temporary markings made directly to the window are not
clobbered by buffered writes stemming from gdisplay_flush_xxx()
routines. clone_tool_paint_func() has been modified to take advantage
of these new states, retiring bug #2184 in a way that does not change
user interface semantics. There are small additions to the PaintCore
interface that do not affect clientele unaware of added semantics.
These changes are detailed at http://idt.net/~gosgood/gimp-patch/patch03.html.
