1135 * Return the size of the string as it would be if it was output properly by
1136 * e.g. TextOut.
1137 *
1138 * This should include
1139 * - Intercharacter spacing
1140 * - justification spacing (not yet done)
1141 * - kerning? see below
1142 *
1143 * Kerning. Since kerning would be carried out by the rendering code it should
1144 * be done by the driver. However they don't support it yet. Also I am not
1145 * yet persuaded that (certainly under Win95) any kerning is actually done.
1146 *
1147 * str: According to MSDN this should be null-terminated. That is not true; a
1148 * null will not terminate it early.
1149 * size: Certainly under Win95 this appears buggy or weird if *lpnFit is less
1150 * than count. I have seen it be either the size of the full string or
1151 * 1 less than the size of the full string. I have not seen it bear any
1152 * resemblance to the portion that would fit.
1153 * lpnFit: What exactly is fitting? Stupidly, in my opinion, it includes the
1154 * trailing intercharacter spacing and any trailing justification.
1155 *
1156 * FIXME
1157 * Currently we do this by measuring each character etc. We should do it by
1158 * passing the request to the driver, perhaps by extending the
1159 * pGetTextExtentPoint function to take the alpDx argument. That would avoid
1160 * thinking about kerning issues and rounding issues in the justification.
