* Request keyboard event reports from global keybindings of other windows This allows mate-settings-daemon to honor global keybindings whenever a different application has keybindings that seem conflicting, but are usually not. For example, an application defining a `Super_L` keybinding and MATE having defining a shortcut that uses the `<Mod4>` key. They are the same physical keyboard, but one is a modifier and the other is not. Without requesting keyboard reports from other windows, the `<Mod4>` shortcuts are swallowed whenever there is a `Super_L` shortcut elsewhere. * Remove KeyReleaseMask as the keybindings_filter only looks at KeyPress * Guard against BadWindow errors
