Summary: Refactor RenderStyle::diff()
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Layout and Rendering
AssignedTo: webkit-unassigned at lists.webkit.org

RenderStyle::diff() is tricky for two reasons.
First, there's nothing to enforce the requirement that "more work" diffs have to be detected before "less work" diffs (i.e. we have to always check for changes that result in StyleDifferenceLayout before changes that result in StyleDifferenceRepaint).
Secondly, in some cases, even when we return, say, StyleDifferenceLayoutPositionedMovementOnly or StyleDifferenceRecompositeLayer, we also need to check for changes that require repaint, and that's not possible now.
