I didn't try and think about an elegant solution at the time.
Why not:
class grfx::Pixmap {
};
class grfx::Image {
public:
grfx::Pixmap & getPixmap();
};
where grfx::Pixmap is an abstract base class. Daughter classes would contain
the Pixmap proper (X) or QPixmap?
I have no real ideas to be honest.

It shouldn't. Once is enough:
Cache & Cache::get()
{
static bool start = true;
if (start) {
start = false;
lyx_gui::init_graphics();
}
// Now return the cache
static Cache singleton;
return singleton;
}
Maybe you could track that down?
