It isn't repeating these concepts in Freetype. Currently, in one (actually two, c and python) implementation, Freetype farms off rendering of OT-SVG glyphs to rsvg, which in turn is cairo-based, to do the actual rendering. FreeType just provides a plug-in system which allows an external library to do the rendering. Basically Freetype gives out the glyph svg outlines etc, and the external library fill in the extent and the actual buffer of a rendered bitmap. This allows any freetype-based applications to use OT-SVG fonts.
