The xrPassthroughStartFB function is defined as:
XrResult xrPassthroughStartFB( XrPassthroughFB passthrough);
Starts an XrPassthroughFB feature. If the feature is not started, either explicitly with a call to xrPassthroughStartFB, or implicitly at creation using the behavior flags, it is considered paused. When the feature is paused, runtime will stop rendering and compositing all passthrough layers produced on behalf of the application, and may free up some or all the resources used to produce passthrough until xrPassthroughStartFB is called.
