Fix issues rendering Cyberbit font

Detail:
  s/Fonts01 - Increase scratchsize from 8K to 12K. 8K was slightly too small for Cyberbit char 0x98f8.
  s/Fonts04 - Fix CachePixels to correctly return any errors generated by CacheChunk
Admin:
  Tested on rev A2 BB-xM.
  Cyberbit char 0x98f8 now renders properly instead of returning a duff error pointer.
