  * Clean up the C bindings by splitting FTGlue.cpp into FTLayoutGlue.cpp, FTGlyphGlue.cpp (unused yet) and FTFontGlue.cpp. C methods previously scattered all around are now located in one of these 3 files. * Hide extern "C" and namespace C constructs in a single FTGL_BEGIN_C_DECLS macro. * Use namespace FTGL all around instead of a mix of C and FTGL namespaces.
