<p>A <a href="trait.Layer.html" title="trait cosmic::iced::daemon::program::graphics::Layer"><code>Layer</code></a> may draw multiple primitive types in a certain order.

The level represents the lowest index of the primitive types it

<p>Two layers A and B can therefore be merged if they have the same bounds,
|

and the end level of A is lower or equal than the start level of B.</p>
