[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.
