From fd36289faa86e92583f014af358f5eca99a3d4aa Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Mon, 26 Apr 2021 09:32:26 +0200 Subject: Remove support for arbitrary rotations There was some unused code-paths for rendering surfaces with an arbitrary rotation applied. This was imported from rootston. Since we don't have plans to make use of this, remove it. --- sway/desktop/output.c | 66 ++++++++++----------------------------------------- 1 file changed, 13 insertions(+), 53 deletions(-) (limited to 'sway/desktop/output.c') diff --git a/sway/desktop/output.c b/sway/desktop/output.c index ab8fd7e8..aa148290 100644 --- a/sway/desktop/output.c +++ b/sway/desktop/output.c @@ -56,26 +56,6 @@ struct sway_output *all_output_by_name_or_id(const char *name_or_id) { return NULL; } -/** - * Rotate a child's position relative to a parent.
