Chris Lord 75f7b3b58c Bug 716403 - Annotate layers with the fixed margins from the PresShell. r=nrc,roc
This annotates fixed layers with the margins that have been applied from
nsIPresShell->GetContentDocumentFixedPositionMargins. Using SyncViewportInfo
in CompositorParent, this allows for async fixed position margin setting.
