From 76073fe5fad8799e5850805f2f090af2cb62c741 Mon Sep 17 00:00:00 2001 From: Berke Güzel Date: Tue, 13 Oct 2026 23:41:31 +0300 Subject: Simplify the public event and CPU API Applications now need far less ceremony: hello.c is a 20-line loop that handles REFRESH, CLOSE and QUIT and draws into the surface's own pixels. - Fold GEOMETRY, STATE and FOCUS into one WINDOW event carrying size, scale and state; unchanged values send nothing. - Guarantee REFRESH once a window has a size and after every resize, never at size zero. - Merge DROP_HOVER into DROP with over/leave/data actions and give drag and drop actions enums. - Keep event strings valid until the next wait and drop yasl_event_release; empty or failed waits report NONE. - Replace copy-in presentation with a lent pixel buffer: yasl_cpu_pixels and yasl_cpu_present. - Remove yasl_poll_event, yasl_cpu_read_pixels, unused event fields and comments that restated names. - Wayland: resize floating windows in request_size instead of reporting it unsupported, and stop marking new GPU surfaces as Vulkan so yasl_vulkan_create_surface no longer fails with NATIVE_WINDOW_IN_USE. Also includes the in-progress public API refactor that was uncommitted in the tree (removal of the app/loop layer, new surface, GL and Vulkan entry points).
