Fix fonts on Big Endian systems, fixes #148

Browse source 
The code used #ifdef __ppc__, probably a leftover from old Mac support,
which apparently doesn't work on all PPC systems (maybe not 64bit PPC).

Now using the LittleFloat() function instead which exists for
exactly this purpose and already handles endianess properly.
