win: release window image before rebind
Previously we try to keep the image data until the rebind succeeds. This way even if the rebind fails, we still have something to display. But that triggers a NVIDIA driver bug. Basically you cannot have more than one names (XIDs) of a window pixmap. NVIDIA driver doesn't like that, and binding the pixmap with its aliases will fail. This can sometimes happen if we name the new pixmap before freeing the old one during rebind, and the pixmap doesn't actually change (i.e. the rebind is unnecessary, could happen because of X event handling complications).
