I wonder if it might be useful to implement a feature to auto re-size region bounding box to the most optimum scale based on visible points? I notice allot, that the size of region can affect build times. Larger region = longer processing times.
If users cull points to what they need, perhaps an auto re-size to most optimum scale might be useful? to save users having to scale, position and orient region bounding box? as well as using the most optimum space.
