Use the ImageMagick flatten command to generate the output all at
once instead of compositing each layer individually, and download
the layers in parallel. On my box, saving roopal27 five times took
a total of 30 seconds before, whereas now it takes 7 seconds. I
expect it to be even better on the production box, where latency
is even lower.
Sharing pane works, everything is great for guests. Logged in
users are on the way, since right now Share Outfit re-saves
anonymously rather than showing sharing data for the existing
outfit.
