It boils down to whether `FT_Outline_Decompose' should return success
for empty glyphs. After the discussion here and some private e-mail
exchanges I'm now rather convinced that the answer is yes – mainly
because `FT_Outline_Check' accepts the empty glyph also.
I'll add a note that users have to filter out empty outlines if
necessary.
