            Bug ID: 215150
           Summary: IOSurface not being recycled after ImageBuffer is
                    destroyed
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: guowei_yang at apple.com

When investigating the code of another project, I realized that whenever we use an AcceleratedImageBuffer (IOSurface backend), the IOSurface was always destroyed with the destruction of ImageBuffer. However, I do believe it makes more sense to put the IOSurface back to surface pool once an ImageBuffer is destroyed. There is actually an existing function, IOSurface::moveToPool implemented, but never used in ImageBuffers. I propose an idea that, we move the IOSurface back to the surface pool in the destructor of ImageBufferIOSurfaceBackend. I am not sure if this change is sufficient, but the current code definitely didn't use IOSurface pool for recycling.
