/**
* Translates Graphics 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 performed 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 we've had 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:
* <p>
* <pre>
* 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()</code>.
