/**
* 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().
