    [GTK][WPE][Skia] Invalid result or crash when painting an accelerated ImageBitmap into WebGL
    https://bugs.webkit.org/show_bug.cgi?id=278908

    Reviewed by Carlos Garcia Campos.

    When using skia, transferring ownership of accelerated ImageBitmaps causes GrDirectContext mismatches
    that lead to problems with reading pixels, drawing etc. Therefore, we need to let ImageBitmap know
    the transfer is happening so that it can act accordingly and e.g. decelerate underlying ImageBuffer.
