* that for ToolbarPanes, layer 0 considered a special default value, and ToolbarPanes on
* layer 0 are pushed to layer 10 automatically. Use Layer 1 for the inner layer as a work-
* around.
*
* Each panel has rows, starting at 0. Each row has positions starting at 0. Each item in a panel
* can have it's row and position set.
*
* Eventually panels will be movable. Each initialization function sets up the panel for this,
* then after a //==// break has additional calls to anchor toolbars in a way that matches
