Description Peter Hutterer 2018-02-02 02:04:17 UTC

Some tablets have BTN_TOOL_PEN (and others) but never actually send the events. We should emulate those internally when we see BTN_TOUCH or a nonzero pressure, as well as enabling the proximity out quirk automatically on those devices.

has evemu recordings for an aiptek tablet that doesn't send those tool events.
