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.

Summary: Change the docs of evas_object_image_load_size_set()/get() since the previous docs were not clear to identify those functions from evas_object_image_size_set()/get()

evas_object_text_clear was no more defined in the headers. Since the
function code is not generated by Eolian, the declaration in the headers
has to be done manually too.
Summary:
This problem occurred due to xkb_keysym_t value of libxkbcommon by e wl server.
e wl server should pass keycode from evdev input device on to wl client.
In order that e wl server receives valid keycode Ecore_Event_Key should have
an extended data member. This patch should be applied with server side patch.
@fix
Test Plan: run e wl server -> create wl client -> type keys

const have been added in object parameter of two legacy APIs to fit
Eolian generated files.
Since these functions retrieve information from object, it is logic that
the object would be const.
in evas_object_image_file_get(const Evas_Object *obj,
const char **file,
const char **key)
remove check for second parameter "file", because it
contradicts comment's statement, that NULL can be passed,
if parameter not needed.
All needed NULL checks of parameter are present inside func.
We need a function in DnD for the overlapping feature to retrieve all
the objects at a specific position.
A private function exists in Evas (evas_event_objects_event_list) for
that purpose.
We need an access to this function for Elementary but we don't
want the is_frozen flag to be checked.
Wayland subsurfaces can be used as video surfaces too, similarly to
Ecore_X windows. However, they support a different set of features. Some
of them, like subsurface clipping and scaling, might be added in the
future, but so far we must work with what we have.
This commit allows to set an enum bitfield to the Video_Surface, with
the default value being one that will keep the same behavior as before,
for Ecore_X window. Thus, backward compatibility should not be broken.
It's possible to inform Evas that the surface in question is not able to
resize or scale, or that it's above or below the original canvas
surface. This allows Evas to show the surface itself, or use a buffer of
pixels instead, when the capabilities are not available.
This function should be used internally by the input system
(Ecore_Evas_Input) to feed Evas with move events. The x,y event info is
relative to the base of the window/surface, instead of the 0,0 of the
canvas.
This case only happens for now under Wayland, where the 0,0 of the
canvas is translated due to the window decorations that are drawn by the
client.
Now, Evas.h includes three new files:
- Evas_Eo.h: Eo API functions (functions defines, enums, base id).
- Evas_Legacy.h: contains the API functions related to objects
- Evas_Common.h: common data (structs, enums...) +
functions not related to objects.
This phase is needed for the EFL 1.8 release to disable Eo APIs if we
consider it is not enough mature to be used by applications.
