[Image-SIG] PATCH: transform(EXTENT) doesn't work for negative x offsets

[Fredrik Lundh]

the transform(EXTENT) and transform(AFFINE) methods
can produce bogus results under certain circumstances.

for EXTENT, this can happen if you're using NEAREST
resampling, and x0 in the (x0, y0, x1, y1) bounding box
is negative.

I've attached a patch.

Cheers /F
