From 90a6fc659f8a842f2460be2742f4e1359848f615 Mon Sep 17 00:00:00 2001 From: Giulio Camuffo Date: Tue, 22 Mar 2016 17:44:54 +0200 Subject: [PATCH] input: use doubles in the interfaces to notify of input events This patch is a further step in the wl_fixed_t internal sanitization. It changes the notify_* functions to take doubles instead of wl_fixed_t but does not change how these are stored in the various input structs yet, except for weston_pointer_axis_event. However this already allows to remove all wl_fixed_t usage in places like the libinput or the x11 backend.
