Fixed some data types/added header files to remove compiler warnings.
Added trivial input data check to FT_Outline_Get_BBox().
Fixed type1z -> type1 file inclusions.
"type1z" -> "type1"
"raster1" -> "raster"
note that I didn't rename all files. We'll have to endure
the "z1..." crazyness unless we perform a _big_ sed on
the sources :-)
