There are several strata that a frame goes into, e.g. background, normal, dialog, tooltip. A strata simply means that all frames in one strata will be rendered above frames in a lower strata, and below frames in a higher strata. | There are several strata that a frame goes into, e.g. background, normal, dialog, tooltip.

Within a strata, each frame has a frame level, which determines the order in which it is rendered. The optimal layout is to have all frames in the same strata at the same frame level, since they can be batched and rendered at the same time. When a "toplevel" frame is clicked on, it is raised above other frames in the strata. | Within a strata, each frame has a frame level, which determines the order in which it is rendered.
