Function buildGridGeometry

buildGridGeometry(cfg?: { divisions: number; size: number }): GeometryArrays
Creates a grid-shaped SceneGeometry.

This function generates the geometry arrays for a grid, which consists of lines along the X and Z axes, creating a grid pattern. The grid can be configured in terms of its size and number of divisions. The function returns the geometry arrays, including vertex positions and indices for drawing the grid.

Usage
```
const gridGeometry = buildGridGeometry({
    size: 10,               // Size of the grid along both X and Z axes
    divisions: 10           // Number of divisions (grid lines) along X and Z axes
});
```
Parameters
- cfg: { divisions: number; size: number } = ...
  Configuration for the grid geometry.
  - divisions: number
    The number of divisions (lines) on the X and Z axes. Default is 1.
  - size: number
    The size of the grid along both the X and Z axes. Default is 1.
Returns GeometryArrays
The geometry arrays for the grid, including positions and indices for the lines.

Throws
If any of the size or division parameters are negative, the function automatically inverts the values and logs a warning.
