  * src/base/fttrigon.c, src/base/ftgloadr.c: Inlude FT_INTERNAL_OBJECTS_H. * src/base/ftstroke.c (FT_Outline_GetInsideBorder, FT_Outline_GetOutsideBorder): s/or/o/ to make it compile with C++ compilers. * src/cache/ftcmru.c, include/freetype/cache/ftcmru.h: s/select/selection/ to avoid compiler warning. * src/cff/cffload.h: s/select/ftselect/ to avoid potential compiler warning. Formatting.
