Disable centering of overviewmap control

Is your feature request related to a problem? Please describe.

I am trying to customize the OverviewMap control, such that the overviewmap remains fixed (i.e., doesn’t zoom, shift, or rotate) when a user interacts with the main map.

The constructor of OverviewMap provides the rotateWithView parameter to enable/disable rotation of the overviewmap. It’s also possible to prevent zooming of the overview map, by only providing a single layer via layers. However, it doesn’t seem to be possible to disable re-centering (OverviewMap.recenter_()].

Describe the solution you’d like

I propose adding a center parameter to the constructor of OverviewMap (true by default), which when set to false would disable centering of the overviewmap relative to the box. In other words, I would like the box to move and the overviewmap to remain static.

Unfortunately, I ran into another issue when trying it with my application, which uses WebGLTile and DataTileSource. If I provide a single resolution resolutions: [res], tile rendering fails here

@hackermd Please open a new issue for this. A short self-contained example would be helpful to reproduce this.

Does this work?

new OverviewMap({
  view: new View({
    constrainOnlyCenter: true, 
    extent: [0, 0, 0, 0],
  },
})

Not tested.
