code for this is ugly (i.e., repetitive) and can probably be easily abstracted/refactored...

use correct y-offset for font positioning

add a flag to drawsymbol/number visfn to allow updating existing objects instead of having to erase/redraw them

Make it possible to just send new attributes to GUI for [drawpolygon] and friends when a field value changes
(This performs better than erasing and redrawing the scalar in the GUI)

slight change to msg/obj box text y-position to keep hanging letters like "g" from overlapping the xlet

match line-height between svg text and div text

add note in todo about potential loss of data when > 4096 bytes of data
are entered into a message box and sent to Pd

remove pentium4 arch (I'm on a MacBook Air-- not sure if that would compile on some other Mac)

* removed a lot of old, commented tcl code
* remove debugging messages
