GameMaker Native Bridge

The Native Bridge is the local bridge library built specifically for GameMaker on Windows 10 and later.

Responsibility split

IGP.GamemakerDesktopBridge.Native.dll - owns the actual desktop connection, event queue, results, and state
GameMaker runtime scripts - wrap the DLL C API into GameMaker function calls

Inside a GameMaker project:

Add IGP.GamemakerDesktopBridge.Native.dll as an Included File
Import the GML runtime script shipped by the adapter (see the windows-auth-achievements sample project)
Call initialize / update / poll_event on a steady rhythm from an object such as obj_controller

Function	Purpose
`igp_gms2_bridge_initialize`	Initialize the bridge
`igp_gms2_bridge_update`	Per-frame driver, usually in Step
`igp_gms2_bridge_poll_event`	Read the next event from the queue
`igp_gms2_bridge_request_game_authorization`	Trigger game authorization
`igp_gms2_bridge_get_desktop_capabilities`	Query desktop capabilities
`igp_gms2_bridge_unlock_achievement`	Unlock an achievement
`igp_gms2_bridge_report_achievement_progress`	Report achievement progress
`igp_gms2_bridge_get_state_snapshot`	Read the current state snapshot
`igp_gms2_bridge_shutdown`	Shut down the bridge

If game authorization or capability queries need to be extended later, continue adding exports at the Native Bridge layer.
