Subject: [PATCH] #3477: Scatter: Scatter Amount takes After Effects' range

Scatter Amount takes 0..1000, After Effects' recorded valid range in the
same units (pixels); the slider stays 0..127. The CPU and GPU renderers move
each pixel by one random offset of up to the amount, so a larger amount
costs the same; samples outside the layer are transparent.
Default and slider are unchanged.
