<Property Grid> and Spatial Reference Frame Issues
A <Property Grid> instance specifies its own SRF primarily to ensure that its "griddedness" is preserved if a consumer asks the API to convert the "native" SRF of part of a transmittal to another SRF.
- During coordinate conversion/transformation between different spatial reference frames, <Axis> gridlines could become distorted so that they are no longer straight lines.
- A <Property Grid> has its own SRF so that it stands apart from any coordinate conversion operations requested by the user.
To connect its spatial reference frame to that of the <Property Grid Hook Point>, a <Property Grid> instance specifies two fields: spatial_axes_count and location_index.
