Depth of Field issues

[MasterBel2]

A couple screenshots:

Widget appears to blur the edges of the object in the foreground with the background; this should not occur. Also appears that certain effects (e.g. aircraft jets) completely ignore depth of field, creating a weird (and somewhat cool) visual glitch.

Widget appears to blur the edges of the object in the foreground with the background; this should not occur -> bind and sample the map and model depth gbuffers (see lava shader for example).

Also appears that certain effects (e.g. aircraft jets) completely ignore depth of field, creating a weird (and somewhat cool) visual glitch. -> this is related to A, airjets seem to write to the depth buffer, disable this via depthmask(false), and b, draw ordering.
