Colin Walters 7bc2f539d0 Explicitly declare internal reserved bits in GdkModifierType
XKB and GDK both add "internal" bits to GdkModifierType.  In C,
this typically doesn't cause problems as bitfields are just integers,
and there's no validation.  However for bindings, it's normal to
convert enumerations to "native" enumeration types, which don't
support unknown bits.  See bug 597292.

* @GDK_MOD1_MASK: the fourth modifier key (it depends on the modifier

* @GDK_MODIFIER_RESERVED_13_MASK: A reserved bit flag; do not use in your own code

* @GDK_HYPER_MASK: the Hyper modifier. Since 2.10
* @GDK_META_MASK: the Meta modifier. Since 2.10
* @GDK_RELEASE_MASK: not used in GDK itself. GTK+ uses it to differentiate
* between (keyval, modifiers) pairs from key press and release events.
* @GDK_MODIFIER_MASK: a mask covering all modifier types.
*
* A set of bit-flags to indicate the state of modifier keys and mouse buttons
* in various event types. Typical modifier keys are Shift, Control, Meta,
* Super, Hyper, Alt, Compose, Apple, CapsLock or ShiftLock.
*
* Like the X Window System, GDK supports 8 modifier keys and 5 mouse buttons.
*
* Since 2.10, GDK recognizes which of the Meta, Super or Hyper keys are mapped
* to Mod2 - Mod5, and indicates this by setting %GDK_SUPER_MASK,
* %GDK_HYPER_MASK or %GDK_META_MASK in the state field of key events.
*
* Note that GDK may add internal values to events which include
* reserved values such as %GDK_MODIFIER_RESERVED_13_MASK. Your code
* should preserve and ignore them. You can use %GDK_MODIFIER_MASK to
* remove all reserved values.
