- Remove mention of "meta" from TabChild. r=roc
- Remove some useless logging. r=roc
- Tag FrameMetrics with its composition bounds at paint time. r=roc
- Add a helper to calculate the render resolution for a FrameMetrics. r=roc
- Add a helper to compute the approximate CSS dimensions a FrameMetrics will cover during composition. r=roc
- BrowserElementScrolling doesn't actually care about zoom or resolution. r=roc
- Accept the viewport that content has calculated, when it's received the latest widget geometry update. r=roc
- Mechanically separate uses of zoom/resolution based on new definitions. r=roc
- Convert GetViewportInfo()'s resolution-dependent scale into resolution-indepedent zoom. r=roc
