I have a GLWidget (OpenGL) based window which is used for displaying
chemical structures. I would like to use this window to generate
thumbnails used as icons for the files containing the chemical structures.
I would like to hide this process of icon generation from the user, so
is there any way that you can
* Show/display a GLWidget/QWidget in some sort of virtual frame
buffer, in such a way that is does NOT appear visual to the user.
* Dump the contents of the invisible window into a pixmap.
