/**
 * Translates Graphics2d calls into escher calls.  The translation is lossy so
 * many features are not supported and some just aren't implemented yet.  If
 * in doubt test the specific calls you wish to make. Graphics calls are
 * always drawn into an EscherGroup so one will need to be created.
 * <p>
 * <b>Important:</b>
 * <blockquote>
 * One important concept worth considering is that of font size.  One of the
 * difficulties in converting Graphics calls into escher drawing calls is that
 * Excel does not have the concept of absolute pixel positions.  It measures
 * it's cell widths in 'characters' and the cell heights in points.
 * Unfortunately it's not defined exactly what a type of character it's
 * measuring.  Presumably this is due to the fact that the Excel will be
 * using different fonts on different platforms or even within the same
 * platform.
 * <p>
 * Because of this constraint you have to calculate the verticalPointsPerPixel.
 * This the amount the font should be scaled by when
 * you issue commands such as drawString().  A good way to calculate this
 * is to use the follow formula:
 * <pre>{@code
 *      multipler = groupHeightInPoints / heightOfGroup
 * }</pre>
 * <p>
 * The height of the group is calculated fairly simply by calculating the
 * difference between the y coordinates of the bounding box of the shape.  The
 * height of the group can be calculated by using a convenience called
 * {@code HSSFClientAnchor.getAnchorHeightInPoints()}.
 * </blockquote>
