Disable depth and stencil buffers

Browse source 
This patch reduces the active GPU memory consumption by disabling the
depth and stencil buffers. During original testing it reduced GPU memory
usage on Linux by almost a third.

This is a reintroduction of previously reverted patch 3475e44.

Closes #2881.
