The only entry to tree redraw is tree_draw() in desktop/tree.c and
first thing it does is plot a flat filled rectangle to the extents of the

Actually I've just noticed that it's been doing that plot even before it
sets the clip rectangle though the plotters. I'll fix that in a second.
However, if that's the reason it's broken, it should have been broken
before, because it's been like that since the treeview branch.
Well, it seems to have fixed it. I had noticed an issue previously
with overdrawing when nodes at the bottom of the tree were expanded -
and that seems to have gone now too.
