first stab at porting core GUI to tkpath with SVG goodness. new scrollbars that will hopefully put an end to the old painful scrollbar nonsense. pdtk_tip clean-up and improvements. tons of other small bug fixes. a number of issues/wishlists still exist before the next big release:
*improve g_array lower/raise to use new functionality (BUG! doesn't match any items)
*scalar is drawn behind at first
*Scope~ window name "h16ffd10" already exists in parent (likely resize hook)
	*Change appearance of the resize hook
*better getrect for scalars inside plot?
*reenable bgerror and t_tkcmd catch
*Clean-up and merge cyclone documentation
