WordIterator's getEnd/getBeginning methods does not support the needs for word boundary detection in text selection. Consider the words AABB (where AA and BB are each words). If getEnd is given the offset on the boundary between AA and BB, it would return that offset since it is the end of AA. For text selection we always want the "next end" if available. This CL adds two methods to word iterator that return the next end and previous beginning. This CL also alters the code in Start/EndHandle to use the x value and current / prev line positions to determine if the user is expanding or contracting the selection.
