This class defines configuration of how a vector layer gets tiled for 3D rendering.
Zoom levels count tells how deep will be the quadtree and thus how many tiles will be generated ( 4 ^ (count-1) ). So for example, for count=1 there will be just a single tile for the whole layer, for count=3 there will be 16 tiles.

Returns number of zoom levels.
One zoom level means there will be one tile. Every extra zoom level multiplies number of tiles by four. For example, three zoom levels will produce 16 tiles at the highest zoom level. It is therefore recommended to keep the number of zoom levels low to prevent excessive number of tiles.
