From 0e86808e5912823f1c6bea1b6d5fcae297fc9f57 Mon Sep 17 00:00:00 2001 From: Tom Englund Date: Mon, 5 Aug 2024 19:58:21 +0200 Subject: cursor: Better xcursor implementation (#7178) * xcursor: bootleg xcursors into its own manager implent XCursorManager and load themes based on librarypath and its dir, now we catch all supplied theme files. and also implent animated cursors. also refactor a bit of spaghetti regarding xcursors in CursorManager. * hyprcursor: fix buffer leak animated cursors are creating a new buffer for each image, ensure we drop the buffers so it continously doesnt build up in infinity. * cursormgr: use eventloopmgr for animation use EvenloopManager for timers instead of adding it directly to m_sWLEventLoop and using its related wl_* functions. ---
