My current implementation uses a helper library called SDL-pango, which 
just handles all Pango stuff and has full control over layouting etc. It 
can do all extent calculations, and then create a bitmap surface. The 
library is not maintained however, and doesn't deal with SDL2 textures 
-- which led me to investigate cairo-pango.
