Output resolution and position
These options tell the Visualizer to only use a part of the screen for its output. In general the
Visualizer output should cover the entire screen. In that case these options can be set to 0, causing the
application resolution to be used. Note that the coordinate system used with these options has its
origin at the bottom-left corner of the screen.

Depth map selection
Many applications use multiple render passes per frame to construct complex scenes. Imagine a game
where a certain room is full of security monitors. The image that is presented on these monitors may
well have been created by a separate render pass. If the game also displays statistics such as health and
the current score on the screen, that is probably a separate render pass as well. The Z-buffer will
often be cleared between render passes like this, meaning the depth that corresponds to the larger
scene (your view of the room) may not be available by the time the frame is ready to be presented.
