/**
 * This test is designed to test Chameleon's ItemLFImpl.lDoInternalLayout()
 * routine only. It does not test label size or content size calculations.
 * It tests label location and content location calculations.
 * 
 * Internal layout for all items is handled in ItemLFImpl.
 * lDoInternalLayout() is given label and content sizes and available
 * width, height, it should place label and content in correct place.
 * Here is what to expect:
 * If label and content are empty, both bounds are set to 0.
 * If label is empty, content is given as much space as it needs but
 *   not more than available.
 * If content is empty, label is given as much space as it needs but
 *   not more than available.
 * If label is a single line label (its height <= label font height) then
 *   there is an attempt to fit label, content and 3 pixel padding between
 *   them on the same line.
 * Otherwise content is placed under label with 2 pixel horizontal padding 
 *   in between.
 *  
 * Furthermore, if label and content are on the same line than
 *   shorter part (label or content) is vertically centered 
 *   against the taller one (content or label).
 * 
 * Then if there is extra space (item can fit in smaller size than
 * it is given) then the space is distributed based on the layout
 * primitives set.
 *
 * ItemLFImpl and Item area abstract in javax.microedition.lcdui.
 * We extend them to test lDoInternalLayout().
