Run cargo update. Remove git dependency on jpeg-decoder (the latest
version was published to crates.io). Update swf-rs to latest to
disable smoothing in SWFv7 and lower (addresses #28).
The current version of jpeg-decoder on crates.io (0.1.15) panics
when encountering a valid JPEG marker of length 2. Some SWF files
contained JPEGs with a COM segment of length 2. This is fixed
on the master branch of jpeg-decoder.
Switch from pixels to twips for internal calculations. swf crate
was updated to add a Twips wrapper-type. Ruffle will use this type
internally for transforms and shapes. This fixes some precision
errors in rendering (see heroes_of_cybertron.swf) and will match
what the Flash Player does internally more closely. (e.g.
DisplayObject x and y will be quantized to 1/20 pixel units). It
is up to the renderer to convert units from twip space to pixels
when rendering.
