Right now our 2d canvas rendering relies on a very old fork of Azure (https://github.com/servo/rust-azure/), which itself relies upon a very old fork of Skia (https://github.com/servo/rust-azure/). The operations that the 2d canvas allows are not complicated and it should be possible to use Pathfinder as the rendering backend instead. This would have several useful results:

• it would remove multiple large C++ codebases from Servo's dependency tree
• it would exercise Pathfinder in a real product
• it would give us hardware acceleration instead of the current software rendering

I'm marking this as "hard" not because I actually believe it will be hard, per se, but it's going to require a bunch of investigation and poking and prodding to understand how to fit Pathfinder into Servo's canvas rendering pipeline. It could be fun, though!
