1022      ter is not number of values in the array of the first one, but an offset
1023      into this description of the pattern. I mean a real *offset* not index

1025      will be first black line *2* units wxCoord, then space 4 units, then the
1026      pattern of *3* units black, 4 units space will be repeated.
