Description:
------------
I submitted this to the maintainer of GD and he said 
that there is a patch for this coming in GD 2.16. It is 
a somewhat obvious bug, so I won't waste time coding up 
examples (if you still want examples, say so...).

In gd.c (ext/gd/libgd/gd.c) line 258 says "ad = im-
>blue[i] - a;" but it should say "ad = im->alpha[i] - 
a;".
