I suppose it would go something like this: first set up the framework of 
the new gfx API on top of the current implementation.  When the subset 
of functionality corresponding to the old API also works under the new 
API, do the inversion, then continue extending/generalising the 
implemention so the new API gets the rest of the functionality it's 
supposed to have.

Yeah.  I'd already written the code from scratch (actually, I reused a 
ton of code), and the new event queues API would've been impossible to 
layer on top of what Allegro has currently.
