Need help changing the cursor icon; I don't have access to winit's Window

[Not-A-Normal-Robot]

three-d doesn't currently seem to change the cursor icon based on egui's output. I know you can set the cursor icon with winit::window::Window::set_cursor_icon but unfortunately I do not have access to the Window because three_d::window::Window::render_loop takes the Window. Does anyone know of a way to set the cursor in this case?
