## Description

This extension allows the application to choose which type of 3D stereo hardware it wants to use so the driver can configure it properly. This configuration is useful for swapchains created from display surfaces because some environments do not have an intermediate windowing system available for easy configuration. This extension will override any stereo type configuration in the windowing system.

For HDMI 3D, only some display modes support stereo rendering, and a new structure is needed to expose that information to the application.
