If ecore get the mouse cancel event(ex: display off, or window stack change) from below, we need to deal with.
Currently, evas also generates up event using evas_event_feed_mouse_cancel function when window hide is called.
if cancel event occurs, ecore also call evas_event_mouse_feed_cancel like window hide situation.
cancel event means all button or touch event should be canceled, but in the future, if we need to deal each cancel event according to touch point,
we need to add api like evas_event_feed_multi_cancel
@feature
this frees the axis data coming in if struct alloc fails - should
basically never happen, but if it does we don't lose axis data as
caller asumes this data will be freed in the event
related to CID 1256115
Some fields (eg. data) may not be properly initialized.
Use calloc() instead of malloc() will ensure proper initialization
even if we add more fields.
These fields (data) would even be passed down to Evas as
Evas_Event_Key_Down for instance.
Summary:
This patch set adds the necessary code to expose device axis state to applications. This was primarily written with graphics tablets in mind, which -- in addition to acting like a mouse -- also provide information about pen pressure, tilt, etc. Other devices could potentially benefit from this API as well: touchscreens, joysticks, knob controllers, "spaceballs", etc.
Whenever an update to the device state is recieved, an "Axis update" event is synthesized. This event contains the updated information, typically scaled and normalized to a particular logical range (e.g. zero to one for pressure, -pi to pi radians for angles, etc.). Information about the tool which generated the event is also stored so that applications can disambiguate events from multiple devices (or in the case of multitouch screens, individual fingers).
This API is only wired up for use with X11 at the moment. Support for other backends (e.g. Wayland) should be easy to add for those familiar them.
**Note**: The following is a list of changes from the "v2" patches originally sent to the mailinglist
//Define and implement new Ecore_Event_Axis_Update events//
* Harcode axis labels instead of including xserver-properties.h
* Use C89-style comments
* Use doxygen comments
* Update comment text to note axes with unbounded/undefined ranges/units
* Create "Ecore_Axis" and "Ecore_Axis_Label" typedefs
* Reference typedef'd instead of raw types
* Adjust how we count through valuators to support tilt/az
* Add support for tilt and azimuth
* Tweak memory management in case number of valuators differ
* Expand TWIST axis normalization to declared range
* Only normalize TWIST axis if resolution == 1 (wacom bug)
* Cache label atoms on first use to minimize round-trips
//Implement EVAS_CALLBACK_AXIS_UPDATE event and friends//
* Update to doxygen comments
* Update comment text to note axes with unbounded/undefined ranges/units
* Typedef 'Evas_Axis_Label', 'Evas_Axis'
* Move typedef for 'Evas_Event_Axis_Update'
* Reference typedef'd instead of raw types
//Wire the Ecore and Evas implementations of axis update events together//
* Expose ecore_event_evas_axis_update in Ecore_Input_Evas.h
* Move ecore_event_evas_axis_update to more logical position
//DEBUG: Add axis update logging to evas-multi-touch.c//
* Removed from patch set
//Make evas-multi-touch demo use new axis functionality//
* Have pressure adjust rectangle brightness instead of size
* Use more available axis data when rendering rectangle (azimuth, tilt, twist)
Test Plan: The evas-multi-touch demo was updated to support axis update events. A graphics tablet was then used to verify that the pressure, azimuth, tilt, and twist data was coming through correctly.

bugfix@: As we have support in the Ecore_Event structure for storing
keycode on key press/release, let's utilize it. This will simplify
wayland compositor code as we won't have to parse key names to get the
keycode.

'data'. If we use it later for XGetAtomName, then we can free if After
we have gotten the atom names and sent the event. (NB: XGetAtomName
will allocate it's own space for the returned name, so this is safe).
