Different drawing for object centers.

Code here did depth test always and depth range 0.0.

There is no real reason for object centers to write and get tested
against depth buffer in this case, just disable the depth test instead
;)

Helps with blurry object centers in depth of field mode too (centers
wrote depth 0 and were always blurry)
