Comment:
I'm slightly nervous about the long-term stability of the apng format, but
given how easy it is to implement and how nice the results are, I suppose
this is a reasonable addition. Some questions/comments:
* I would expect a method named `APngAssembler.frame` to return a frame.
Would `add_frame` or `append_frame` or something similar be a better name
for this?
* Since the docstring of `APngAssembler.__init__` won't appear in the
manual, it might be more useful to move that information to the class
docstring.
* most of the `APngAssembler` methods are missing doctests.
* Not sure if it's part of this ticket, but I really think

converting a generator to a list when rendering frames] is a bad idea.
When there are lots of very large frames, this becomes becomes time and
memory intensive. What advantage do you see?
