 *
 * This should include
 * - Intercharacter spacing
 * - justification spacing (not yet done)
 * - kerning? see below
 *
 * Kerning.  Since kerning would be carried out by the rendering code it should
 * be done by the driver.  However they don't support it yet.  Also I am not
 * yet persuaded that (certainly under Win95) any kerning is actually done.
 *
 * str: According to MSDN this should be null-terminated.  That is not true; a
 *      null will not terminate it early.
 * size: Certainly under Win95 this appears buggy or weird if *lpnFit is less
 *       than count.  I have seen it be either the size of the full string or
 *       1 less than the size of the full string.  I have not seen it bear any
 *       resemblance to the portion that would fit.
 * lpnFit: What exactly is fitting?  Stupidly, in my opinion, it includes the
 *         trailing intercharacter spacing and any trailing justification.
 *
 * FIXME
 * Currently we do this by measuring each character etc.  We should do it by
 * passing the request to the driver, perhaps by extending the
 * pGetTextExtentPoint function to take the alpDx argument.  That would avoid
 * thinking about kerning issues and rounding issues in the justification.
