1118 * yet persuaded that (certainly under Win95) any kerning is actually done.
1119 *
1120 * str: According to MSDN this should be null-terminated. That is not true; a
1121 * null will not terminate it early.
1122 * size: Certainly under Win95 this appears buggy or weird if *lpnFit is less
1123 * than count. I have seen it be either the size of the full string or
1124 * 1 less than the size of the full string. I have not seen it bear any
1125 * resemblance to the portion that would fit.
1126 * lpnFit: What exactly is fitting? Stupidly, in my opinion, it includes the
1127 * trailing intercharacter spacing and any trailing justification.
1128 *
1129 * FIXME
1130 * Currently we do this by measuring each character etc. We should do it by
1131 * passing the request to the driver, perhaps by extending the
1132 * pGetTextExtentPoint function to take the alpDx argument. That would avoid
