Minor speedups for 3D view text drawing ~10-15% improved frame-rate with particle display.

- ascii text drawing functions, slightly faster since they dont have to do hash lookups & utf8 conversions for each char.
- used ascii drawing functions for the view3d's number display.
- each text item was using fixed 128 chars, now only allocate the string length needed.
