Subject: [PATCH 3/4] [mtwebster] xadapter.vala: Remove XkbKeyTypesMask and
 fields from XKbChangeMap call.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This was originally a workaround for xFree86 4.3 - see:
https://bugzilla.gnome.org/show_bug.cgi?id=673547
​
As of https://gitlab.freedesktop.org/xorg/xserver/-/commit/87c64fc5b0 this
causes a BadLength error when attempting to use shifted characters.
