1040 * Return the size of the string as it would be if it was output properly by
1041 * e.g. TextOut.
1042 *
1043 * This should include
1044 * - Intercharacter spacing
1045 * - justification spacing (not yet done)
1046 * - kerning? see below
1047 *
1048 * Kerning. Since kerning would be carried out by the rendering code it should
1049 * be done by the driver. However they don't support it yet. Also I am not
1050 * yet persuaded that (certainly under Win95) any kerning is actually done.
1051 *
1052 * str: According to MSDN this should be null-terminated. That is not true; a
1053 * null will not terminate it early.
1054 * size: Certainly under Win95 this appears buggy or weird if *lpnFit is less
1055 * than count. I have seen it be either the size of the full string or
1056 * 1 less than the size of the full string. I have not seen it bear any
1057 * resemblance to the portion that would fit.
1058 * lpnFit: What exactly is fitting? Stupidly, in my opinion, it includes the
1059 * trailing intercharacter spacing and any trailing justification.
1060 *
1061 * FIXME
1062 * Currently we do this by measuring each character etc. We should do it by
1063 * passing the request to the driver, perhaps by extending the
1064 * pGetTextExtentPoint function to take the alpDx argument. That would avoid
1065 * thinking about kerning issues and rounding issues in the justification.
