Good work, thanks.  Patch applied with a couple of changes: I renamed 
cairo_pdf_ft_font_remap_composite_glyphs to 
cairo_pdf_ft_font_remap_composite_glyph since it's only remapping one 
glyph at a time and I added a comment about why the glyf table has to be 
the first we write out.

Yes, but not subsetting.  That shouldn't be a problem, though, since 
Type1 fonts are restricted to 255 glyphs.  My plan was to just embed the 
Type1 font directly, but I haven't yet figured out how to get at the raw 
font data given an FT_Face using the public freetype API.

Yeah, thanks, I've added that.
