Well, I would strongly suggest against emitting text as trapezoids :-)

I think you'll have to accept some device dependent variation of
text; downloading client side fonts is the right way to do text,
so you have a guaranteed font, but you don't have any real guarantees
about how the rasterizer will rasterize it in detail.

I don't know if that has implcations for what variation to accept
