/*
* All JMenuItems (and JMenus) include enough space for the insets
* plus one or more elements. When we say "icon(s)" below, we mean
* "check/radio indicator and/or user icon." If both are defined for
* a given menu item, then in a LTR orientation the check/radio indicator
* is on the left side followed by the user icon to the right; it is
* just the opposite in a RTL orientation.
*
* Cases to consider for SynthMenuItemUI (visualized here in a
* LTR orientation; the RTL case would be reversed):
* text
* icon(s) + text
* icon(s) + text + accelerator
* text + accelerator
*
* Cases to consider for SynthMenuUI (again visualized here in a
* LTR orientation):
* text + arrow
* (user)icon + text + arrow
*
* Note that in the above scenarios, accelerator and arrow icon are
* mutually exclusive. This means that if a popup menu contains a mix
* of JMenus and JMenuItems, we only need to allow enough space for
* max(maxAccelerator, maxArrow), and both accelerators and arrow icons
* can occupy the same "column" of space in the menu.
*
* A quick note about how preferred sizes are calculated... Generally
* speaking, SynthPopupMenuUI will run through the list of its children
* (from top to bottom) and ask each for its preferred size. Each menu
* item will add up the max width of each element (icons, text,
* accelerator spacing, accelerator text or arrow icon) encountered thus
* far, so by the time all menu items have been calculated, we will
* know the maximum (preferred) menu item size for that popup menu.
* Later when it comes time to paint each menu item, we can use those
* same accumulated max element sizes in order to layout the item.
