Subject: 'r' to Rotate.
X-Git-Url: http://git.scottworley.com/picsort/commitdiff_plain/59a0fba182b1c592474e3c3c01730917b51828ea

'r' to Rotate.

This is janky.  The rotation is applied immediately, but changing the
src attribute to load new image data takes longer, so the two are not
applied at the same time.
