Title: lazy update shouldn't change zoom level

Upon more extensive testing I realized this is a bad
idea as it is causing the clusters to disappear when
zooming via click or mouse wheel. In fact setting zoom
here is completely unneeded. Tested this with clustering on
and off, its working great and providing a good boost in
performance.
