[Feat] MVTLayer Cartesian Coordinates

[s-n-i]

Target Use Case

MVTLayer incorrectly visualizes a vector tile dataset in Cartesian coordinates in OrthographicView.

I would like to make MVTLayer compatible with this use case.

Proposal

Changing the modelMatrix like this results in correct visualization:

I was wondering if MVTLayer is already intended to support Cartesian coordinates because it appears to infer a Cartesian coordinate system from !this.context.viewport.resolution in the source code here. If Cartesian coordinates are already intended to be supported, I can change this issue to a bug ticket.
