Use older FreeType2 installed in the system

This issue was created automatically from an original Mantis Issue. Further discussion may take place here.

The system FreeType2 of Mac OS X 10.3 is freetype-2.1.0 (2002-04). Some cpp macro constant defined by ftimage.h are slightly different from recent FreeType2. For example, FT_GLYPH_FORMAT_BITMAP was not defined at that time, and ft_glyph_format_bitmap was used. Such uncapitalized macros are defined in recent FreeType2 too, for backward compatibilities. Therefore, it is possible to support both of older & recent FreeType2 by using uncapitilized macros. Although it would not be realistic to use such old system (and old freetype2), I wish VTK maintainers can consider the patch like this:
