If my image uses the 3857 projection and contains data for a specific region (e.g., `[40, 0, 120, 60]` as `minX`, `minY`, `maxX`, `maxY`), and I am implementing it using a Mapbox GL custom layer, how should the `matrix` be used in the vertex shader?

Description
If my image uses the 3857 projection and contains data for a specific region (e.g., `[40, 0, 120, 60]` as `minX`, `minY`, `maxX`, `maxY`), and I am implementing it using a Mapbox GL custom layer, how should the `matrix` parameter in the `render` method be used in the vertex shader?
Thanks！

Research direction
Start by reading the Mapbox GL custom-layer render entry point and the vertex shader that receives the matrix parameter. Determine what guidance or example is needed for a 3857 image covering the stated region, and consider the work done when the matrix usage is clearly documented for this case.
