Initial pass on API stability guarantees This introduces -DWLR_USE_UNSTABLE and adds information regarding the stability status to all headers. I started with a conservative set of headers to mark as stable: - types/wlr_matrix.h - util/edges.h - util/log.h - util/region.h - xcursor.h

render: define EGL_NO_PLATFORM_SPECIFIC_TYPES (#2452) This avoids Xlib.h inclusion via EGL headers. See [1] for discussion. This change is based on a Weston commit [2]. [1]: https://github.com/KhronosGroup/EGL-Registry/pull/111 [2]: https://gitlab.freedesktop.org/wayland/weston/commit/526765ddfdfd

render/egl: include EGL/eglmesaext.h only if present This patch will make the EGL renderer work on any EGL/GLESv2 driver providing the EGL_WL_bind_wayland_display extensions. Mesa used to declare provisional EGL_WL_bind_wayland_display directly in <EGL/eglext.h>. Then, all unofficial extensions were moved to <EGL/eglmesaext.h>, to have a cleaner implementation. See: https://gitlab.freedesktop.org/mesa/mesa/-/commit/ab7bb10a2af711086319ce35815acd797b86fe27 The extension was then approved at Khronos Group, and reached the official <EGL/eglext.h>. See: https://www.khronos.org/registry/EGL/extensions/WL/EGL_WL_bind_wayland_display.txt https://github.com/KhronosGroup/EGL-Registry/commit/aa9b63f3ab18aee92c95786a2478156430f809e4 In order to make sure the renderer will work on any version of any implementation providing the extension, only include the mesa-specific header if it's present.

Remove all wayland-server.h includes The documentation for wayland-server.h says: > Use of this header file is discouraged. Prefer including > wayland-server-core.h instead, which does not include the server protocol > header and as such only defines the library PI, excluding the deprecated API > below. Replacing wayland-server.h with wayland-server-core.h allows us to drop the WL_HIDE_DEPRECATED declaration.

render/egl: add support for EGL_EXT_device_drm_render_node This EGL extension has been added in [1]. The upsides are: - We directly get a render node, instead of having to convert the primary node name to a render node name. - If EGL_DRM_RENDER_NODE_FILE_EXT returns NULL, that means there is no render node being used by the driver.
