Subject: [PATCH] Bugfix: warp pointer during the EnterNotify-disabled phase

Following bug:
1) Assign workspace 9 to output HDMI2
2) On HDMI2, be on workspace 1
3) Focus a different output, say LVDS1
4) Execute i3 'workspace 9'
5) Something happens, but you end up back on ws 1

(this is due to an EnterNotify being generated when warping)
