Collect @viewport before constructing RuleSets.
- Move ViewportStyleResolver to StyleEngine.
- Only create a ViewportStyleResolver for top level documents.
- Collect @viewport rules via the DocumentStyleSheetCollection.
- Use the initial viewport size for resolving viewport relative
lengths.
- Introduce initialViewportChanged() and viewportRulesChanged() in
StyleEngine to trigger re-collection and resolution of the actual
viewport. These currently trigger an immediate call to updateViewport
which will later be a part of the document lifecycle phase for
updating active stylesheets.
This finally fixes issues 332763, 455136, and 463098.
