Layer

A layer (or DRAWLAYER ) orders each within a, affecting how they overlap. There are five named layers, in the order they are drawn (back to front):
 * BACKGROUND
 * BORDER
 * ARTWORK
 * OVERLAY
 * HIGHLIGHT (see details)

Two widgets in the same layer may be further ordered using a sublayer (or textureSubLevel ) specified numerically from -8 to 7 (back to front).

Details

 * When one frame is in front of another (according to its Frame Strata), all of its LayeredRegions will also be in front -- in otherwords, layers are part of each frame.
 * Setting causes HIGHLIGHT to show/hide as the cursor hovers the Frame.
 * Transparent overlapping textures display different results depending on their relative ordering. For consistent results, use a blend mode of ADD or MOD on both textures.

Example
Construct a Texture inside the "ARTWORK" layer of a.
