From 582825eda792c2612ab6f43a14ccb2bea3aee5d4 Mon Sep 17 00:00:00 2001 From: Phil Jones Date: Mon, 6 Mar 2023 21:27:16 +0000 Subject: Add fractional scaling support. The main change is that we now always have to set up the dummy surface which was previously only used when multiple monitors were present. This is because there's no way to determine an output's fractional scale factor without displaying a surface on it, and we need to know the scale factor before we create our main window surface. The extra compositor round-trips lead to a slight slowdown for single monitor setups (to the same speed as multi-monitor setups), but it's currently unavoidable as far as I know. --- src/wp-fractional-scale-v1.c | 73 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 73 insertions(+) create mode 100644 src/wp-fractional-scale-v1.c (limited to 'src/wp-fractional-scale-v1.c') diff --git a/src/wp-fractional-scale-v1.c b/src/wp-fractional-scale-v1.c new file mode 100644 index 0000000..0eb72f8 --- /dev/null +++ b/src/wp-fractional-scale-v1.c @@ -0,0 +1,73 @@ +/* Generated by wayland-scanner 1.21.0 */ + +/* + * Copyright © 2022 Kenny Levinsen + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
