## TRSChunkLoader.BuildGraph
```pascal
function TRSChunkLoader._BuildGraph(map: TMufasaBitmap; white, red: TPointArray): TWebGraphV2;
function TRSChunkLoader.BuildGraph(name: String; map: TMufasaBitmap): TWebGraphV2;
```
Magically builds a webgraph for you for a given collision map passed into `map`.

The collision map can only have 4 colors:
- white ($FFFFFF) for walkable space
- black ($000000) for non walkable space
- red ($0000FF) for doors (optional)
- gray ($333333) for objects (optional)

```{note}
This is an internal method. Don't use it if you don't know what you are doing.
