This patch unifies the behavior of the scale node by removing the arbitrary limit of scaling images. The change applies to scale and transform nodes. Note: with this change, Blender can crash for large resizing factors (around 10 000 x 10 000 relative factors). We think it's very unlikely users will run into this issue, so we agreed errors coming from failed memory allocation won't be handled, as is the case for GPU compositor.
