1021      ter is not number of values in the array of the first one, but an offset
1022      into this description of the pattern. I mean a real *offset* not index
1023      into array. I.e. If the command is [3 4] 1 setdash   is used, then there
1024      will be first black line *2* units wxCoord, then space 4 units, then the
1025      pattern of *3* units black, 4 units space will be repeated.
