◆ getZoomLevels() [2/2]

Computes start and stop level.

If align to grid is on levels are based on projection grid; else, stop zoom level is 0, start is the full res level.

Parameters

proj
aoi
sourceGsd	Full res gsd of input.
zoomLevels	Intitialized by this.
fullResGsd	Intitialized by this to the highest resolution of zoom levels. This may or may not be the same as the sourceGsd.
