Author: Emil Velikov <[email protected]> Date: Thu Sep 28 18:38:13 2017 +0100 wayland-egl: rework and simplify wl_egl_window initialization Use calloc instead of malloc + explicitly zeroing the different fields. We need special handling for the version field which is of type const intptr_t. As we're here document why keeping the constness is a good idea. The wl_egl_window_resize() call is replaced with an explicit set of the width/height.
