/**
* Provides a mapping from the document model coordinate space
* to the coordinate space of the view mapped to it.
*
* @param pos the position to convert >= 0
* @param a the allocated region to render into
* @param b the bias toward the previous character or the
* next character represented by the offset, in case the
* position is a boundary of two views.
* @return the bounding box of the given position is returned
* @exception BadLocationException if the given position does
* not represent a valid location in the associated document
* @exception IllegalArgumentException for an invalid bias argument
* @see View#viewToModel
