Summary

Layers are the primary 'Drawing' mechanism in the WoW UI, and allow WoW to display all of its visible UI elements on the screen. Layers work by defining a list of <Layer> elements, each of which define a 'Z order' level, and define which LayoutFrames should be drawn at that 'level'. A layer works by listing Texture and FontString elements each of which can draw itself based on how its defined. The cumulative effect of all the Layers in the Layer list, combined with their FontString and Texture elements, will render the all the visible elements for a Frame at runtime.

Example

<Frame name="MyFrame">
  <Layers>
    <Layer>
      <Texture>
        <Size x="100" y="100" />
        <HitRectInsets>
          <AbsInset left="0" right="-100" top="0" bottom="0"/>
        </HitRectInsets>
        <Color a="1" r="1" g="1" b="1" />
      </Texture>
      <Texture>
        <Size x="100" y="100" />
        <Color a="1" r="1" g="1" b="1" />
      </Texture>
    </Layer>
  </Layers>
</Frame>

This example will show a frame with several textures.
