* 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
