* egui_web: always use the glow painter, and remove the old WebGL code. * Clean up the WebPainter trait * Clarify WebGL1 warning text in color test The glow painter became standard in egui 0.17, and I've heard no complaints! So let's simplify and go all in on glow. Part of https://github.com/emilk/egui/issues/1198
