From 98c774f1c0f3fc4891c9dd6fc2dbe67bb70938d6 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristian=20H=C3=B8gsberg?= Date: Mon, 22 Jul 2013 14:33:42 -0700 Subject: [PATCH] compositor: Move device coordinate transform helper to compositor.c This function transform input coordinates from output space to compositor space and is useful for X input as well as touch screen input. --- src/compositor-x11.c | 67 +++++----------------------------------------------- src/compositor.c | 51 +++++++++++++++++++++++++++++++++++++++ src/compositor.h | 4 ++++ 3 files changed, 61 insertions(+), 61 deletions(-) diff --git a/src/compositor-x11.c b/src/compositor-x11.c index 5a0bcf0..51ae35d 100644 --- a/src/compositor-x11.c +++ b/src/compositor-x11.c @@ -1059,61 +1059,6 @@ x11_compositor_deliver_button_event(struct x11_compositor *c, } static void -x11_output_transform_coordinate(struct x11_output *x11_output, - wl_fixed_t *x, wl_fixed_t *y) -{ - struct weston_output *output = &x11_output->base;
