* In the next few methods we call |mParent->SendInvalidateAll()| - that has

* to render again, that means we keep trying to get a good device and swap
* chain and don't block the main thread (which we would if we kept trying in
* a busy loop because this is likely to happen in a sync transaction).
* If we had to recreate our device, then we have new textures and we
* need to reupload everything (not just what is currently invalid) from the
* client side. That means we need to invalidate everything on the client.
* If we just reset and didn't need to recreate, then we don't need to reupload
* our textures, but we do need to redraw the whole window, which means we still
* need to invalidate everything.
* Currently we probably do this complete invalidation too much. But it is better
* to do that than to miss an invalidation which would result in a black layer
* (or multiple layers) until the user moves the mouse. The unnecessary invalidtion
* only happens when the device is reset, so that should be pretty rare and when
* other things are happening so the user does not expect super performance.
