LibGUI: Partially restore original TreeView column painting behavior

Browse Source 
TreeView now prints columns mostly like it used to. The paddings are now
properly applied, though. focus_rect drawing has been gated behind a
selection_behavior() check to make sure we don't draw a focus rect
around the column text when we're supposed to draw it over the entire
row.
