Image decoding is now done in a bg thread
Continuing from the previous commit, this shifts:

* In-memory data -> temporary file
* Image decoding -> background thread

The background thread asynchronously decodes frames and
sends them to the render thread via a bounded channel.

While decoding frames, it writes them, uncompressed, to
a scratch file so that when the animation loops, it is
a very cheap operation to rewind and pull that data
from the file, without having to burn CPU to re-decode
the data from the start.

Memory usage is bounded to 4 uncompressed frames while
decoding, then 3 uncompressed frames (triple buffered)
while looping over the rest.

However, disk usage is N uncompressed frames.
