Depth Effect that I use for DOF in post processing

Edit of shader depth addon by ilikecreepers, I've happened to edit it a bit for my own use in those artsy-fartsy things as I thought it would help me save time compared to using fog + blackify.

Linked video here goes over how to use it. Effect can be activated through "Post processing" tab in gmod's Q menu, in the effects tab, also, as long as the effect is active, your HUD won't be drawn.

Original addon mentions that it won't work when you're driving vehicles, I didn't happen to check if that still applies to this edit, but it probably does.
