           Summary: DrawingBuffer has unused functions
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Minor
          Priority: P3
         Component: WebGL

Since the removal of Chromium code in r147775, these functions have not been used in any platform.  They don't do anything, or they just return false and are never called, so I suggest they be removed.

DrawingBuffer::prepareBackBuffer,
DrawingBuffer::requiresCopyFromBackToFrontBuffer,
DrawingBuffer::paintCompositedResultsToCanvas, and
DrawingBuffer::clearPlatformLayer
