 - Added `Device::drm_device_node_path()` and `Device::drm_render_device_node_path()` getters to EGL via `EGL_EXT_device_drm`.
 - Added support for `DrmDisplayHandle` in EGL's `Display::with_device()` using `EGL_DRM_MASTER_FD_EXT` from `EGL_EXT_device_drm`.
 - Properly set up OpenGL-specific stuff on the `NSView`, instead of relying on Winit to do it.
+- Added `OpenHarmony` platform support with EGL.
