Subject: [PATCH 1/3] ENH: add input surface scaling (issue #514)

- surfaceFeatureExtract
  * dictionary "scale" entry

- triSurface
- triSurfaceLoader
  * optional scaleFactor on reading

- surfaceAdd
- surfaceBooleanFeatures
- surfaceClean
- surfaceCoarsen
  * scale option

- surfaceTransformPoints, transformPoints
  * scale option as scalar or vector quantity
