Minor changes. 

* src/base/ftobjs.c (FT_Load_Glyph): Use the recrusive call with
`FT_LOAD_NO_SCALE' so that the loaded data is unscaled.

* src/base/ftobjs.c (FT_Render_Glyph_Internal): Change the format
to bitmap once an SVG glyph is successfully rendered.

* src/sfnt/ttsvg.c (tt_face_load_svg_doc): Make sure metrics are
grabbed. Scale `horiAdvance' and `vertAdvance' properly and
convert them to 26.6 format.
