            Bug ID: 253655
           Summary: [GPU Process] Have one copy of NativeImage when it is
                    shared between WebProcess and GPUProcess
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Images

Since WebProcess has to share the local PlatformImage with GPUProcess through ShareableBitmap, we can get rid of the local PlatformImage and have both processes use the ShareableBitmap. Also for GPUProcess, we can ensure we decode the PlatformImage for sizeForDrawing instead of decoding it for the full size.
