Description [src]

Creates a session that renders the map to an OpenGL surface.

The object is ready once maplibre_native_ffi_render_session_ready_async finishes, which fails with the errors that the completion reports.

See mln_map_attach_open_gl_surface in the C API reference.

It fails with these errors:

MAPLIBRE_NATIVE_FFI_ERROR_UNSUPPORTED when maplibre_native_ffi_open_gl_supported_context_provider_mask() lacks the context’s platform.
