fonts
* fix slow start caused by font fixed/proportional enumeration
- fixed point evaluator moved to separate thread during first
instantiation of Font_Browser class. Actual time to enumerate
2650 fonts on an i5 3.2 GHz system is approximately 25
seconds. Background process does not effect UI, but selection
of fixed fonts in font browser dialog may not show all of the
fixed fonts until the evaluator thread exits.
