SSS fixes:

- Radius R, G, B sliders had too small number increase on clicking.
- Preview render now renders with higher SSS error setting to speed it up a
  bit.
- bug #6664: 3d preview render had artifacts. re->viewdx/dy wasn't set then,
  which is needed to estimate the area of each point. Have set this now, not
  in the nicest way, there is some bit duplicated code, but I don't want to
  refactor existing code with the chance of breaking it at this point.
- bug #6665: grid like artifacts with parts rendering. The two extra pixels
  around parts used for filtering were used as well, leading to double points.
