#define RETRO_ENVIRONMENT_GET_HW_RENDER_CONTEXT_NEGOTIATION_INTERFACE_SUPPORT (73 | RETRO_ENVIRONMENT_EXPERIMENTAL)
/* struct retro_hw_render_context_negotiation_interface * --
* Before calling SET_HW_RNEDER_CONTEXT_NEGOTIATION_INTERFACE, a core can query
* which version of the interface is supported.
*
* Frontend looks at interface_type and returns the maximum supported
* context negotiation interface version.
* If the interface_type is not supported or recognized by the frontend, a version of 0
* must be returned in interface_version and true is returned by frontend.
*
* If this environment call returns true with interface_version greater than 0,
* a core can always use a negotiation interface version larger than what the frontend returns, but only
* earlier versions of the interface will be used by the frontend.
* A frontend must not reject a negotiation interface version that is larger than
* what the frontend supports. Instead, the frontend will use the older entry points that it recognizes.
* If this is incompatible with a particular core's requirements, it can error out early.
*
* Backwards compatibility note:
* This environment call was introduced after Vulkan v1 context negotiation.
* If this environment call is not supported by frontend - i.e. the environment call returns false -
* only Vulkan v1 context negotiation is supported (if Vulkan HW rendering is supported at all).
* If a core uses Vulkan negotiation interface with version > 1, negotiation may fail unexpectedly.
* All future updates to the context negotiation interface implies that frontend must support
* this environment call to query support.
