Christoph Reichenbach 7c80ac6df7 API for pressure-sensitive pens + XInput2/Wayland ... This patch adds an API for querying pressure- sensitive pens, cf. SDL_pen.h: - Enumerate all pens - Get pen capabilities, names, GUIDs - Distinguishes pens and erasers - Distinguish attached and detached pens - Pressure and tilt support - Rotation, distance, throttle wheel support (throttle wheel untested) - Pen type and meta-information reporting (partially tested) Pen event reporting: - Three new event structures: PenTip, PenMotion, and PenButton - Report location with sub-pixel precision - Include axis and button status, is-eraser flag Internal pen tracker, intended to be independent of platform APIs, cf. SDL_pen_c.h: - Track known pens - Handle pen hotplugging Automatic test: - testautomation_pen.c Other features: - XInput2 implementation, incl. hotplugging - Wayland implementation, incl. hotplugging - Backward compatibility: pen events default to emulating pens with mouse ID SDL_PEN_MOUSEID - Can be toggled via SDL_HINT_PEN_NOT_MOUSE - Test/demo program (testpen) - Wacom pen feature identification by pen ID Acknowledgements: - Ping Cheng (Wacom) provided extensive feedback on Wacom pen features and detection so that hopefully untested Wacom devices have a realistic chance of working out of the box.		2023-11-12 09:52:02 -08:00
