            Bug ID: 274399
           Summary: [CG] Optimize getting the ImageFrame metadata
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Images
          Assignee: webkit-unassigned at lists.webkit.org

BitmapImageSource::cacheMetadataAtIndex() currently makes separate calls to ImageDecoder functions. Some of them calls CGImageSourceCopyPropertiesAtIndex() and we end up calling CGImageSourceCopyPropertiesAtIndex() multiple times.

This can be optimized by having a single function in ImageDecoder to fill in the ImageFrame metadata. So we can make a single call to CGImageSourceCopyPropertiesAtIndex() and use its CFDictionary to retrieve all the ImageFrame metadata.
