Detailed Description

A non-rendering alternate for the main compositor that still can support applications fully.

Monado's design is highly modular, including allowing alternate compositors to be used. If you are looking to write an additional or alternate compositor to the one in src/xrt/compositor/main, this code is your starting point. It is the basic implementation of xrt_compositor_native extracted from there, renamed, and with most implementations removed. Compare with similarly-named files there to see what was removed, and what helper functionality has been factored out and may be reusable. For example, you may be able to use comp_renderer, comp_resources, comp_shaders, and comp_target, among others.
