+Subject: [PATCH] Map both gdk's Meta and Alt to vte's Meta for >=gtk+-3.2.2
+ compatibility
+
+Also, since VTE_META_MASK is now a mask with multiple bits set, code that
+compares gdk key modifiers to VTE_META_MASK by numerical equality is no
+longer guaranteed to work. Therefore, for such comparisons a new function,
+vte_keymap_fixup_modifiers, is introduced; it ensures that if any bits
+matching matching VTE_META_MASK are set, then all are set.
