[PATCH olpc-bootanim 0/2] add tool to convert deltas back to individual images

[Sascha Silbe]

This is a one-shot tool (i.e. I needed it just once and am not really
interested in maintaining it), but maybe somebody else has some use for it in
the future...

Usage:
- put frame00.565 and deltas in current directory
- <wherever>/deltas/undelta.py
- for x in $(seq -f %02.f 1 25) ; do
    ffmpeg -vcodec rawvideo -f rawvideo -pix_fmt rgb565 -s 1200x900 -i frame"$x".565 -f image2 -vcodec png frame"$x".png
  done

(thanks to Mike Dawson for the ffmpeg invocation[1]!)

Sascha Silbe (2):
  .gitignore: only ignore the images/deltas file, not the deltas
    directory
  add undelta.py tool for splitting out individual images from deltas
