Pillow: Heap out-of-bounds write `Image.paste()` / `Image.crop()` via signed coordinate overflow

Summary Pillow's public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits. In 4-byte pixel modes such as RGBA, this becomes a controlled backward heap underwrite: for a source image of width W, Pillow writes 4 W...
