            Bug ID: 219666
           Summary: [GPU Process]: Cache WebFonts in GPUP
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Canvas
          Assignee: webkit-unassigned at lists.webkit.org

The WebFont will be cached the same way we cache and reference the NativeImage.

When recording DrawGlyphs, we will ensure the Font is cached by GPUP and we will use its RemoteResourceIdentifier in the DL item.

When replaying back the DL in GPUP, we are going to pass the FontHashMap to DisplayList::Replayer so its replay() method can resolve the RemoteResourceIdentifier back to a Font.
