Subject: ecore_drm: Add pointer warping API
X-Git-Tag: upstream/1.20.0~7398
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ddc6962d775345ccb0eb4590486693efb3564075;p=platform%2Fupstream%2Fefl.git

ecore_drm: Add pointer warping API

Adds a new API: ecore_drm_device_pointer_warp() which warps the pointer
to the specified location.  All libinput seats with pointers are warped.
