Scale does not affect spot coordinates

The scale factor should affect spot coordinates such that project ground surface distances and grid distances (i.e. as seen via spot coordinates) should differ by the scale factor.

Unfortunately right now it seems as though Revit treats the designer as designing in map grid coordinates which is not correct.

To replicate:

1. Draw a wall of (ground surface) length 100m.
2. Set up IFC epsg.
3. Set IFC map conversion scale of 2.
4. Do a spot coordinate at both ends of the wall.
5. The difference in spot coordinate eastings/northings will be 100m. This is wrong.

Reproduce the issue using the five steps in the report, then trace how the IFC EPSG and map conversion scale are applied to spot coordinates. Done means a wall with a map conversion scale of 2 produces spot-coordinate differences that reflect the scale factor rather than remaining at 100m.
