I don’t see why people should stop using the PNG API when it’s working 
for them (ie. the files are known to be PNG.)

But I agree it would be great to have easy-to-use code for loading 
images in many formats into cairo. I hope cairocffi.pixbuf can be it, 
for Python. GDK-PixBuf is used in GTK+, and is thus packaged everywhere.

(By the way, the code shouldn’t be too hard to adapt to pycairo, if 
compatibility with PyGTK or PyGObject is required.)
