[Bf-python] Nice smooth fonts in bpython

[Campbell Barton]

Hi. I just thaught Id see if I could get BIF_GetStringWidth working, Was 
very easy for the most part, now my console can display nice smoothed fonts.
but the BIF_GetStringWidth always returns 0, no idea why. it seems to 
take the same parms as BIF_DrawString.

Drawing AA text works fine, getting the string width returns 0.
- Wondering if anyones interested in having a look.
