Summary: Move text drawing routine to tcl

Initial Comment:
It's best let tcl to figure out how to draw text and the border box. This should fix non-latin text drawing like Chinese.

Message:
This patch is definitely the right approach going forward (instead of
generating Tcl commands on the C-side, calling Tcl procs from C).  Part of
the problem though is that the mouse tracking is still handled on the
C-side, and this patch makes the boxes smaller than the original size. 
Therefore if you clikc just above or below the box, Pd still uses the old
measurements (now in pd-gui.tcl) as the basis for determining what was
clicked on, and you'll get the menu for that object that was just below
where the mouse clicked rather than the menu for the canvas that was just
clicked. 

I think this patch could be useful now if it used the box measurements in
pd-gui.tcl, and then fit the font into them.  As for the bug with the
Chinese text not fitting in the boxes, my guess is that its related to the
UTF-8 code, something like each chinese character is made up of multiple
bytes, and some piece of code is still measuring one character equals one
byte.
