[PD-dev] text placement

[Hans-Christoph Steiner]

Thanks much.  I'll take a look.  But now after fiddling with  
different fonts, it seems that its the fonts themselves that have  
different placement.  Bitstream Vera Sans Mono seems to be too high  
up.  Lucida Grande looks much better:

Since I am on the topic, I thought I'd post about what I did to get  
the same size boxes on each platform.  It's pretty simple actually, I  
just hardcoded the values, eliminating all the Tcl/Tk and Pd that  
tries to guess the box size based on font measurements.  Basically,  
the Courier font that is provided on each platform is not the same  
font at all.  They are all different heights and widths.  So the way  
around this is to use the exact same font on each platform.  That's  
why I choose Bitstream Vera Sans Mono.  It is available under a BSD- 
ish license and works on all platforms.  I originally thought that a  
mono-spaced font was necessary, but after seeing Lucida Grande, I  
think a proportional font works nicely.
