IMHO, it would be two things:

- make Pd vanilla do what Pd-extended does in terms of box sizing

- or, even better, make pd send pd messages to pd-gui instead of Tcl,  
and move GUI size, mouse, click, etc handling to pd-gui.  Then we get  
zoomable GUIs and all sorts of other good things.  Big project tho

Ah, I see.  It turns out that 0.43 is actually correct.  If you  
compare the same text in a native Mac OS X program like TextEdit, use  
plain text mode, and make sure its using Monaco for the font.  Then  
you'll see that 0.43 is actually the same as TextEdit, while in 0.42,  
the font is slightly smaller than it should be, therefore looking  
fuzzy or anti-aliases.  Monaco is a font that is not anti-aliased at  
many sizes.
