      Description

      A UI with a large number of (usually small) effects often can't be effectively batched by the renderer. One approach to solving this might be API for ShaderEffectSource and/or item.layer, such that a set of source items are drawn to a common atlas.

      For example:

      Text {
          text: "Hello World"
          layer.enabled: true
          layer.atlas: "TextAtlas" // or reference to an Atlas item?
          layer.effect: ...
      }

      where the above would result in the text being rendered into a shared atlas, and that atlas becoming the source texture for the effect.
