First of all, a big thanks to Werner and Antoine for their latest work !!
* src/pshinter/pshalgo2.c (psh2_hint_table_init),
src/pshinter/pshalgo1.c (psh1_hint_table_init): removed compiler
warnings
* include/freetype/cache/*, src/cache/*: yet another massive rewrite of
the caching sub-system, in order to both increase performance and allow
simpler cache sub-classing. As an example, the code for the image and
sbit caches is now much simpler
I still need to update the documentation in www/freetype2/docs/cache.html
to reflect the new design though..
