1019 Here, I'm afraid you do not conceive meaning of parameters of 'setdash'
1020 operator correctly. You should look-up this in the Red Book: the 2nd parame-
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.
