1154 Line style - WRONG: 2nd arg is OFFSET

1156 Here, I'm afraid you do not conceive meaning of parameters of 'setdash'
1157 operator correctly. You should look-up this in the Red Book: the 2nd parame-
1158 ter is not number of values in the array of the first one, but an offset
1159 into this description of the pattern. I mean a real *offset* not index
1160 into array. I.e. If the command is [3 4] 1 setdash is used, then there
1161 will be first black line *2* units wxCoord, then space 4 units, then the
1162 pattern of *3* units black, 4 units space will be repeated.
