/**
 * Builds a test that maps a device pixel to its `[lon, lat]`, or `null` when the
 * pixel is not part of the visible map. It combines two clips that `projection.invert`
 * alone misses:
 *
 * - the **post-clip** (cartesian) stream rejects device pixels outside the clip
 *   rectangle — relevant once the map is panned/zoomed with a `clipExtent`;
 * - streaming the inverted coordinate **back** through the projection applies the
 *   pre-clip (spherical) boundary and checks the round trip: azimuthal projections
 *   clamp `invert` outside the visible disk to the limb, and those clamped points do
 *   not project back to the pixel they came from.
