-@subsection model_specific_configuration_huion_tablets Graphics tablets without BTN_TOOL_PEN proximity events
-
-On graphics tablets, the BTN_TOOL_PEN bit signals that the pen is in
-detectable range and will send events. When the pen leaves the sensor range,
-the bit must be unset to signal that the tablet is out of proximity again.
-Some HUION PenTablet devices are buggy and do not send this event. To a
-caller, it thus looks like the pen is constantly in proximity. This causes
-unexpected behavior in applications that rely on tablet device proximity.
-
-The property LIBINPUT_MODEL_TABLET_NO_PROXIMITY_OUT may be set
-by a user in a local hwdb file. This property designates the tablet
-to be buggy and that libinput should work around this bug.
-
-Many of the affected tablets cannot be detected automatically by libinput
-because HUION tablets reuse USB IDs. Local configuration is required to set
-this property. Refer to the libinput model quirks hwdb for instructions.
-
-This property must not be used for any other purpose, no specific behavior
-is guaranteed.
