 Q: Why Canvas drawings seems to happen in random order?</br>
-A: Canvas drawing is highly asynchronous operation and subsequent `CanvasElement::draw()` operations may not get updated in the order you have called them. The solution is either make a single draw call where all items are updated once, or use `CanvasElement::draw_completed()` to wait until each draw has happen. `CanvaElement::draw_completed()` should be used for animations (or game like frequent updates) instead of timers for updating the graphics. Like this [example](https://github.com/mmertama/Gempyre/blob/6ef49c831c39f8dd67a0cd656f26dae4a2ff46e0/examples/fire/src/main.cpp#L100)

 Q: How to do multiple `Gempyre::FrameComposer` in a single draw? My second draw is not visible</br>
-A: Do you call erase? See `GempyreCanvas::draw_completed above. You may also try to call your drawn in a `Ui::after` timer with 0ms delay, that should ensure the correct drawing order.
