            Bug ID: 225088
           Summary: Refactor the FilterEffect result buffers into a new
                    class named 'FilterImage'
           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
          Reporter: sabouhallawa at apple.com

This moves all the conversion from ImageBuffer to the unpremultiplied/premultiplied ImageData and vice versa from FilterEffect to FilterImage. This will help with the following:

1. Simplifying the FilterEffect geometry calculation and give the ability to save memory
2. Integrate CoreImage in FilterImage and give the ability to deal with non CoreImage filters seamlessly through FilterImage.
3. Prepare for applying the FilterEffects in GPUP.
