little reproducer

There is a problem when we draw gdAntiAliased line, which has a negative 'dy', i.e. coordinates y1 > y2. It can be reproduced with a reproducer attached:
$ gcc -o reproducer790400 reproducer790400.c -lgd
$ ./reproducer790400 >reproducer790400.png

Actual results:
reproducer790400.png contains a black box

Expected results:
reproducer790400.png contains almost vertical line
