Came across this is issue when testing some ICs consisting of a galaxy against a low resolution background.

We should only update the depth_h of a particle after applying the upper and lower bounds to it during the drift. Else, the depth_h can become invalid in some rare cases where the correction by the minimal and maximal values is quite large.
