confusion, grid snap is now the default as it seems to be the most wanted and easy to use mode. Absolute grid snapping happens in a somewhat generic function 'applyGridAbsolute', which could also be used for objects and other transforms later on. It is conceptually similar to the 'project' snapping option, in that it calculates a delta vector for each element on top of the overall transform, which places each node on the grid. Node transform now uses the top-left node corner for TransformData->loc. The transform center is still the average of node centers, so that scaling and rotation works nicely. snapGrid*** functions have been renamed to snapGridIncrement*** to distinguish better between incremental and absolute grid snapping.
