            Bug ID: 241793
           Summary: Remove local bounds from DrawGlyphs and
                    DrawDecomposedGlyphs display list items
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Process Model
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: heycam at apple.com

These fields exist only because the localBounds() function on display list items doesn't have access to the relevant resources, only the resource ID. This patch passes the resource heap into localBounds() so that DrawGlyphs and DrawDecomposedGlyphs can compute bounds on the fly. This lets us avoid sending the bounds over IPC too.
