(Solved) Is it possible to hide buildings/wonders from the world view? (XML or DLL)

[Synthlight]

Does anyone know how/if it's possible to hide the buildings/wonders so they are hidden from view on the map? I don't want the building itself to be completely invisible; it should still be buildable/demolishable/listable from within the city management I just want to 'hide' it from interfering with the city layout. (i.e. I just want cites to be filled with whatever the generic building of the era is.)

I did some digging and my best guess for doing this in XML is 'DisplayPosition' but I can't find much on how that works so I don't know if this is the right way.

Now I pleasantly discover that the DLL/source is available and am wondering if that provides an easier solution?
If I were to alter "m_iPreferredDisplayPosition = kResults.GetInt("DisplayPosition");" (in 'CvBuildingClasses.cpp, CvBuildingEntry::CacheResults') would that possible work? If I override this to 0 will buildings be invisible or will only slot 0 be displayed? (Is -1 valid or will that ruin/crash things?)

Does anyone know where the function is for actually displaying buildings in the world view?

PS: I'm no stranger to C/C++ or Lua I just have no idea how this works in relation to Civ V modding.

update DisplayPosition to 0 in xml will hide these

the code in DLL:
void CvCity::setupWonderGraphics()
{
...
int iPreferredPosition = buildingInfo->GetPreferredDisplayPosition();
if(iPreferredPosition > 0)
// the code update wonder/building graphics only when DisplayPosition > 0

Thanks that works beautifully.

I went with altering 'GetPreferredDisplayPosition()' to 'return 0;' so it hides everything.
