1085 * Kerning. Since kerning would be carried out by the rendering code it should
1086 * be done by the driver. However they don't support it yet. Also I am not
1087 * yet persuaded that (certainly under Win95) any kerning is actually done.
1088 *
1089 * str: According to MSDN this should be null-terminated. That is not true; a
1090 * null will not terminate it early.
1091 * size: Certainly under Win95 this appears buggy or weird if *lpnFit is less
1092 * than count. I have seen it be either the size of the full string or
1093 * 1 less than the size of the full string. I have not seen it bear any
1094 * resemblance to the portion that would fit.
1095 * lpnFit: What exactly is fitting? Stupidly, in my opinion, it includes the
1096 * trailing intercharacter spacing and any trailing justification.
1097 *
1098 * FIXME
1099 * Currently we do this by measuring each character etc. We should do it by
1100 * passing the request to the driver, perhaps by extending the
1101 * pGetTextExtentPoint function to take the alpDx argument. That would avoid
1102 * thinking about kerning issues and rounding issues in the justification.
