The internal implementation of the

drawImage(img, dx1, dy1, dx2, dy2, sx1, sy1, sx2, sy2, obs)

method call can incur integer overflow if any of the dimensions is large
enough to overflow a signed integer. The dimensions in this case are
the differences abs(dx2 - dx1), abs(dy2 - dy1), abs(sx2 - sx1), abs(sy2 - sy1).

The resulting overflowed result will cause us to ignore the operation even
though the results are quite reasonable. In some cases the miscalculation
can cause us to throw an exception for otherwise valid data.
