#629 Incorrect stroke width with rotation

[Ali Lakhia]

I'm using GraphicsMagick on OS X, with homebrew. I'm using version 1.3.35. Noticed that if I draw lines with various rotation angles, some lines honor the stroke width but some are much thinner. I created a shell script which demonstrates the problem that I have attached to this ticket. I'm also attaching the output that I got.

Thank you for your time and consideration.
