The title of this bug is misleading. I think, it should be changed -

FROM :
"Negative width/height values not always treated properly by 2D canvas drawImage"

TO :
"Negative 'x' and 'y' co-ordinate values not treated properly by 2D canvas drawImage"

               OR

Canvas drawImage() does not work as expected when the source-rect specified in the drawImage() call, is not completely inside the source-image.

For example, consider a source-image with width=50, height=50.
Suppose the source-rect is (0, 0, 100, 100) where x=0, y=0, width=100, height=100. Now, source-rect should be right-clipped, and after clipping, the source-rect should be (0, 0, 50, 50).
