 *
 * wxAuiPaneInfo.ToolbarPane() and .Defaults() are used to clear and then prepare the objects so
 * only use them once at the beginning of configuration..
 *
 * Panels are organized in layers, from 0 (close to the center) and increasing outward. Note
 * 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
 * present functionality.
