Subject: [PATCH] Fix crash after OpenGL::detach in the presence of buffered
 child components

The crash fixed by this commit could be triggered by attaching an OpenGL
context to a component, calling setBufferedToImage (true) on one of its
child components, and then detaching the OpenGL context from the parent.

Since 4ba01a80a0b25a258d3236887ab690a292a7d055 we are creating images
with the current rendering context's native image type, so the above
scenario would leave an image buffer that references the detached
context.
