Log message:
Added caching of kerning values for characters from 32 to 127.
The cache is about 100kb, but it gives a reasonable boost for font rendering
in system memory or hardware accelerated. We could make it configurable.
"df_dok --draw-string --system" went from ~305 KChars to ~358 KChars on an
Athlon 1.33GHz. I guess the boost will be even bigger on ARM 50MHz with a G200.
Using A8 fonts, that look well now, on an Athlon 1.33GHz with a G550:
Anti-aliased Text 3.00 secs ( 945.85 KChars/sec)
A bit smaller font and we have a million anti aliased characters per second ;)
