Font constants

[Jesse Ross]

Hey everyone!

Perhaps someone can easily answer this question for me. Do we have font  
constants, similar to Mac OS X? As I'm doing a new UI theme, I want to  
make sure I'm using fonts at the appropriate sizes (I know, I know,  
Alex, 12pt Bitstream Vera Sans) in the right places. Here is Apple's  
HIG on the issue:

OSXHIGuidelines/XHIGText/chapter_4_section_2.html

Any info or pointers in the right direction would be much appreciated!

Thanks!
