v3.3.0: Gestures, Shortcuts, and External Controllers

This is a big user facing update for Handheld Daemon, just after Ally X support was added. It adds gestures and shortcut support, both to open the overlay and Steam UI, and enhances external controller support.

New Features

• Gesture/Shortcut Support that are customizable
  • Touch Screen Gesture support Left/Right/Bottom
  • Keyboard Shortcuts While Gamescope is open (Left Meta Press, Hold, Ctrl+3, Ctrl+4)
  • All controllers: Xbox + B
  • All shortcuts do not interfere with touchscreen/device operation and are completely transparent.
  • They work regardless of DE (apart from keyboard which is blocked when Gamescope is not running).
  • Through the use of event bitmasks we achieve:
    • No additional CPU utilization, apart from a modest increase when touching the screen
    • Privacy assurance, as only the Meta, Ctrl, 3 and 4 buttons are hooked for the keyboard
• Per gesture/shortcut you can choose from the following (get in touch with suggestions!):
  • Open the Steam Keyboard (default: bottom swipe)
  • Steam Overlay (default: left bottom swipe, recommended: Meta Hold, although not default)
  • HHD Overlay (default: left top third swipe)
  • Steam QAM (default: right bottom swipe, recommended: Meta Press, although not default)
  • HHD QAM (default: right top third swipe, recommended: Xbox + B, although not default)
• For swipes, orientation needs to be added per-device.
  • Configurator is included (open issues / get in contact)
  • Ally/Ally X Supported
  • Legion Go supported
  • GPD Win 4 / Max supported
• Finally, external controller interception allows for enhancing overlay controller support
  • External controllers work both in desktop and overlay, regardless of Steam Input profile
  • Both XInput and DInput controllers are supported.
  • HID controllers such as Dualsense with native Steam/Emulator support will still leak through to the game and steam.
  • Pre-alpha Kernel IOCTLs should help with overlay support, and are hidden behind a feature flag.
