[PATCH 1/3] compositor: Import input structs and helper functions from wayland
Kristian Høgsberg
krh at bitplanet.net
Mon Apr 29 14:23:36 PDT 2013
We now rely on 1.1.90 for the wayland-server library without the input
structs and focus helper functions. Include the code from wayland in
compositor.h and new files data-device.c and input.c.
