Selfsampler snapshot

Performance of profiler treetables displaying a big amount of data (rows) is poor, eventually blocking the EDT when scrolled down. Sampled snapshot attached.

Caused by a bug in BasicTreeUI.paintVerticalPartOfLeg() which incorrectly sets the dotted vertical line to be rendered from the top of the tree (should be from the top of the actual rendering clip) when the root node is hidden (JTree.setRootVisible()) - this is the case for all profiler views.

Affects the Windows LaF and any other BasicTreeUI-based LaFs which render horizontal lines in trees.
