* gdesktop.c (click_proxy_motion): Terminate rubberbanding if the event mask does not contain GDK_BUTTON1_MASK. There is a race condition where we will not get the button release event if we manage to grab the server in the button_press handler before the window manager proxies the button release to us. (perform_release): New function to terminate rubberbanding; this used to be in click_proxy_button_release(). Also, update the drag selection based on the last known mouse position, not on the current one (which is not meaningful if the race condition mentioned above kicks in). (click_proxy_button_release): Use perform_release().
