Comment 8 for bug 695035

This problem may also pertain to the space requirements of other elements (buildings and immovables).
(I had similar problems with the boulders I created (currently called standing stones "sstones)

The reserved space on the map is not sufficient to accomodate the house models (existing as well as new ones) without conflicts. While in some cases the layering in the Z-axis keeps up the illusion of "behind", it distroys it in other cases. Those conflicts cannot be resolved by only changing the hotspot. Animation of carriers and animals usually kill the illusion.

To reproduce: build a house (I used the new Empire bakery) and build roads as close as possible before the builder arrives. Watch the building animation (groundplate) and look at the working animation after the worker has occupied the house.

To demonstrate the problem I have prepared a montage (attached).
It shows in 2 rows a building sequence of Chuck's new imperial bakery model.
The upper row shows building at the normal (adjusted by Chuck) hotspot.
The lower row shows an alternative hotspot chosen (by me) to solve the conflict by moving the building closer to its flag.
The problems are marked. I have found no hotspot that could avoid all conflicts.

The answer to this may be, to be more generous in reserving that space, but that others must decide.

The montage will show that the hotspot cannot be used for _major_ tweaking of the positioning, because the
delivery of wares will break the Z layering.
