Just making a specific color transparent is NOT recommended, as in
generally a color will have anti-aliased edges or other problems.

However for a green rectangle, there should be no problems, if you had
used intergers for the retangles pleacement.

As for the actual problem the others are right.  do the transparency
first, then draw the lines over that.
