1067 *
1068 * This should include
1069 * - Intercharacter spacing
1070 * - justification spacing (not yet done)
1071 * - kerning? see below
1072 *
1073 * Kerning. Since kerning would be carried out by the rendering code it should
1074 * be done by the driver. However they don't support it yet. Also I am not
1075 * yet persuaded that (certainly under Win95) any kerning is actually done.
1076 *
1077 * str: According to MSDN this should be null-terminated. That is not true; a
1078 * null will not terminate it early.
1079 * size: Certainly under Win95 this appears buggy or weird if *lpnFit is less
1080 * than count. I have seen it be either the size of the full string or
1081 * 1 less than the size of the full string. I have not seen it bear any
1082 * resemblance to the portion that would fit.
1083 * lpnFit: What exactly is fitting? Stupidly, in my opinion, it includes the
1084 * trailing intercharacter spacing and any trailing justification.
1085 *
1086 * FIXME
1087 * Currently we do this by measuring each character etc. We should do it by
1088 * passing the request to the driver, perhaps by extending the
1089 * pGetTextExtentPoint function to take the alpDx argument. That would avoid
1090 * thinking about kerning issues and rounding issues in the justification.
