BuildingFloorCoordDict

THIS IS OBSOLETE. Keep for historical information.
The footprint of buildings when: under construction; completed construction; rubble; plus there burning versions, are now defined as shown here:
https://codebyfire.com/colonists/wiki/index.php/ModsUnityAssetBundles#Specific_Hierarchies

This entry in render.json controls the building footprint shown during, and after, construction - relative to the respective image file (e.g. buildingfloor_201_L1.png and buildingfloor_201_L2.png).

The X and Y values note the building entrance tile.

Note that some buildings (BoatYard, Harbour, Large Harbour, FishingHut, probably any building using PIER - "layerTypeToCreate": 3) will ignore buildingFloorCoordDict as buildings over water use their 3D assets for rendering the "floor". (this may be obsolete - placeholder to verify)
Example entry in render.json

{
  "buildingFloorCoordDict": {
    "201": {  // building ID
      "LEVEL_1": {  // building level 1
        "x": 1, // x coord of entrance
        "y": 0 // y coord of entrance
      },
      "LEVEL_2": {  // building level 2
        "x": 0, // x coord of entrance
        "y": 0 // y coord of entrance
      }
    }
  }
}

Building footprint files should include 128 x 128 pixels for each tile.
buildingfloor_201_L2.png would contain the floor for building of ID=201 at level=2.
