Changes

You can hack on WebRender either via a checkout of mozilla-central or via a checkout of the webrender repository. Using mozilla-central allows you to easily build/test Firefox and trigger try pushes, especially when you have interdependent changes across Firefox and WebRender. You can also build standalone WebRender from within mozilla-central, via i.e.

cargo build --features=capture,replay,pathfinder

cd /path/to/m-c

cd /path/to/webrender

git checkout -b my_branch
