SpecificationNone

Summary

*This is not a web-exposed change.* The implementation of
CanvasRenderingContext2D's measureText(), fillText(), and strokeText() has
a drastic change. This might affect performance, so we'd like to run an
origin trial so canvas-heavy applications can try out the new
implementation.
