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:
DND does not work in X11 because we cannot set type.
The f8e036d5af causes this.
Since the xdnd type list does not exists at the beginning,
if we always return without setting new property, we cannot set dnd type.
This patch brings dnd work again by correcting the type set operation.
@fix
Test Plan: Try dnd tests in elementary_test.

so this is a re-try at the evas gl destination alpha fix. this is what
cedric tried, but done RIGHT. it required adding an ecore_x call to
create a window with correct visual/colormap. it requires doing
visuals totally correctly all the way from ecore_evas to the evas
gl_x11 core. nvidia drivers are very picky about visuals. i also had
to vid the egl/gles code too to do the same thing. nvidia gles/egl
drivers are also picky, mesa is not. this all requires a lot of code
changes. it's far from trivial
this isn't backported for a few reasons:
1. verify this fix doesn't break for anyone.
i tested:
nvidia glx + egl/gles
intel glx + egl/gles
radeon glx
it needs wider testing. nouveau, fglrx for starters and maybe
some other gles/egl drivers.
2. have some review time
3. time to settle before blasting to stable branches

this fixes drm vsync discovery when you have both drm and nvidia
drivers seemingly present in /dev but the intel drivers are the dri
ones and nvidiactl is there (who knows if it's used). keep the nvidia

there is a kernel oops when using vboxvideo 4.3.14 and one calls
drmWaitVBlank(), then do not init drm when using such driver.

It seems that when things go wrong it does happen that we start with i == 0. It
will then have been walking into info[-1] 'happily'. Changing the test, to first
decrement and then compare should stop that issue.
This should @fix T1467.
this uses a thread to collect vsync input events and filter them
before forwarding them to the mainloop (as a double timestamp). this
means wakeups only happen for the actual vsync and thus animator and
not for other screens we are filtering out anyway. this should fix the
continual animator wakeups that happen if you have a dri/drm based
driver and > 1 screen.
due to mesa changes to hide dri2 symbols, i have had to work on a fix
that makes this work again by going right to drm. now it works and
animators shoudl be vsynced on drm drivers if possible (only 1 card -
use card 0). already existing nvidia solution that uses a lot more
memory is there. others - no support. timers only
this adds a slave process that is useful on nvidia drivers as there
isn't another way to get vsync evenys (that i know about). i need to
make another slave process to that includes a dri2 protocol
implementation since mesa has now hidden its dri2 symbols.
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.

this technically adds a feature - it adds non-mitshm support for
ecore_x image grabbing, but that fixes a bug. it doesn't touch xcb

this fixes T1127 andshould probably be backported.
@fix: Fix building Enlightenment without X support
These changes are needed so that we can build Enlightenment without X
support. Many places in the E code reference
Ecore_X_Atom/Ecore_X_Icon. If we build E without X support, these end
up being undefined, causing build to fail, so we need to predefine them.

Summary:
The window auxiliary hint is the value which is used to decide
which actions should be made available to the user by the WM. If you
want to set specific hint to your window, then you should check whether
it exists in the supported auxiliary hints that are registered in the
root window by the window manager.
Once you've added an auxiliary hint, you can get a new ID which is used
to change value and delete hint. The window manager sends the response
message to the application on receiving auxiliary hint change event.
A list of auxiliary hint within the Ecore_Evas has this format:
ID:HINT:VALUE,ID:HINT:VALUE,...

This fixes valgrind reporting lost bytes when selecting text (e.g. in entry).
Can be reproduced in any program that has entry:
Simply run it with valgrind, select any text, and then exit.
Fixed by properly freeing the selection data, since it is either cleared or replaced.
Also, changed argument in sizeof since it didn't match the type of selections[in].
Summary: The window manager rotation allows the WM to controls the rotation of application windows. It is designed to support synchronized rotation for the multiple application windows at same time.

apparently I read the commit order wrong and this fix went in for 1.4.0, not 1.3.2, which means anyone who has 1.3.2 has been having lots of fun crashes for the past 24 hours
this was a fixme which was likely written sometime before July 2010 when the bug was fixed, just prior to the 1.3.1 release. I think it's probably okay to require that release since it's been 3+ years.

If the property was successfully fetched the number of items stored in
val is returned, otherwise -1 is returned.

Being annoyed by different types of eina critical macros - CRI, CRIT,
CRITICAL -, I concluded to unify them to one. Discussed on IRC and
finally, CRI was chosen to meet the consistency with other macros -
ERR, WRN, INF, DBG - in terms of the number of characters.
If there is any missing bits, please let me know.
size_ret is used later as an argument for malloc, so it should be
positive. In addition this should ensure that
ecore_x_window_porp_property_get returns a positive value and is true if
we malloc data.
Hopefully also fixes CID 1135636
As bounds is a pointer, bounds + num will always be postive, so this is
an eternal loop. In addition, XFixesInvertRegion only accepts one
region, so num must be 1.
Fixes CID 1039469
Data returned from ecore_x_window_prop_property_get are malloced, so use
free, not XFree. Which also is consistent, as free was used on other
occasions.
I give up. people continually complain about these and submit them as crashes, so now they're only visible if you set ECORE_X_SYNC. the next step is an #ifdef ISCOMFITOR.
NB: Cannot really happen for 1.8 (as --disable-ecore-x-randr has no

the ECORE_X_SYNC environment variable exists to make ecore-x debugging synchronous.
printing X errors as they occur is useful for application developers; errors should not
be silenced just because they are inconvenient or plentiful.
because an error with no idea where it came from since its async is
pretty much usless noise. if you want this to be useful you literally
need to do an xsync every x call and be able to get backtraces... the
xsync then would be inside ecore-x. and of course this would be so
nastily slow that you need to make it an option at build...
allocate space for 'data'. If we return before using it, then free
'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
