just some idea: what about removing sping and agg altogether ?
The code will be simpler and bug reports also, because it's clear
which backend is used.
Questions:
1) I don't know if there is a feature/backend which isn't supported
   by cairo ?
2) Is the cairo quality sufficient (cairo itself , not the actual
   implementation in rdkit)? 
3) speed (when used for many images)
4) ...
