I'm not sure if there is a single best-practice recommendation; I've
certainly had good experience using DevIL in the past, though I have
never used it with cairo. It's interesting that DevIL only provides
IL_RGBA and IL_BGRA; the documentation annoyingly states that these
formats are "self explanatory", which they are not. Maybe IL_BGRA
happens to be compatible, if they're talking about byte order?
