Print Setting Term Definitions

Are there official definitions for these terms in the ZSuite Print Settings?

1) Support angle - measured with respect to what?

2) Support Lite - how much "lighter" is this than standard support and how does it figure which support to make lighter?  Does it eliminate some support and not others?

3) Avoid holes - what does this actually do?

4) Surface layers - is this the number of solid layers on the bottom before support starts printing and the number of solid layers on top after support stops printing?

5) Offsets - do the settings determine how much larger that inner contours ( diameters for holes) prints compared to the design dimension and how much smaller diameters are for rods?  How are inner and outer contours defined - just holes and rods or something more?
