This callback must be manually destroyed and removed on
ecore_evas_hide(), because it won't be delivered anymore after the
surface is destroyed. If the callback still exists, the engine will find
it and avoid doing a new redraw until it is finally called.
Maybe the correct thing to do is to keep this callback in the
Ecore_Wl_Window struct, and have some functions to set/unset it, so it
gets destroyed when the window is hidden. Or when the surface is
destroyed.
We must unset it, so the Evas engine knows that it has to do all the
setup to destroy the EGL surfaces associated with it. And in the case of
an ecore_evas_show, recreate everything again.
Fix phab T392.
Notice that it should reopen T359, as it wasn't really fixed, but a
rotation with resize was being used when a non-resized rotation was
requested. The cause of the "protruding surfaces" is likely the fact
that Elementary is setting the opaque regions manually, instead of
leaving it to Ecore_Evas. This must be fixed either inside Elementary
itself, or adding the "surface extents" (shadow/non-visible surface
parts) info to Ecore_Evas too.
This reduces code duplication for ecore_evas resize routines inside
wayland engines by using a common _ecore_evas_wl_common_resize
function as the resize code for both engines was the same anyway.

These two APIs will save the title and class_name inside

is received, we are sure that all the registry bind requests done so
far were processed already, and that the registry and globals are
available and can be used.
Now, on the functions that request interfaces or registry, we call
_ecore_wl_init_wait(), which will check if the callback was received
already (that means that all requests inside the init were processed).
If it was not yet, then we wait until receiving that callback, before
returning the requested data.

When moved mouse among two objects having cursor set,

so that newly added cursor object was detached.
It is needed to set the engine internal borderless property.
Also update the border (frame) object, showing/hiding it as needed, and
updating the framespace size when the frame object is handled by the
engine.
If this Ecore_Evas already has a mouse inside it, there's no need to
send an additional mouse in event.
Additionally, always send a mouse_move event before a mouse_down, so the
Evas pointer position can be updated properly before the mouse down.
Now the opaque and input regions are updated on ecore_wl_window_resize,
there's no need to call ecore_wl_window_buffer_attach() for this

The checks on alpha and transparent flags were also fixed.
ecore_wl_window_update_size() is now called by ecore_wl_window_resize(),

If Ecore_Evas is requested to draw its own frame, then set the

Instead of moving the objects by adding the framespace offset to them,
use this offset when rendering them. This way there's no change in the
object's geometry/position, it works correctly with map, and will be
automatically updated in case that the framespace values change (for
instance if one sets a window to borderless).
There are 2 main places where changes were needed:
- output redraws, when they come from an object being changed, must be
add the framespace offset to their damaged area;
- checks to see if the object is inside a given rendering area, must
also add this offset, since the object is actually being rendered on
a different position;
Add 4 rectangles to be used as border of the window, instead of a single
rectangle under the framespace. This allows to move the frame object to
the top layer, instead of staying on the lowest layer. With the frame
over the other objects, there's no need of framespace clipper object,
which causes several bugs.
The frame should not stay in the same layer as the other objects. If the
application wants to allow it to be on top of the content, then it must
provide a custom frame object and set it to that layer.
NOTE: Should we make Elementary's be on a lower layer too?
The real canvas size contains enough space for rendering the frame, but
ecore_evas_geometry_get() should be consistent accross all the engines
and report only the client area.
Maybe we should switch to use -Wno-unused-parameter in our default cflags?
I mean unused parameters are really common and I do not see their harm.
Using -Wno-unused-parameter would let us remove all the cluttered EINA_UNUSED
and __UNUSED__ and also be safe when a paramter gets is use later as the
compiler could optimize it out when tagged with unused. Still we would avoid
the warnings to find the important ones.
Jenkins as well as klocwork complained here as data is already used for
the parameter of the function and we shadow it here locally. Does not look
like it would really harm us here but better avoid it.
When creating windows directly with Ecore_Evas, instead of using
Elementary, a default smart object is provided for the frame (client
side window decorations).
Now this smart object inherits from the clipped smart object, which
means that all its member objects will be clipped to its main clipper,
being skipped when the framespace clipper checks for objects without a
clipper.
Fix a ticket, which I don't remember the number because trac doesn't
work.
It is a very tricky things to get header order right on windows. Having that
order only in .c files simplify the work a lot. So let's try to do it with
Ecore_Evas after it rewrite and split into modules.
This will update the edges info inside the Evas_Engine_Info, and make it
correctly resize to the top/left if needed.
Also call ecore_wl_window_buffer_attach() on the egl engine, since it's
needed after the ecore_wl_window_update_size().
This will force the window to correctly update its size when the event
is received by the compositor, rather than just after an
ecore_evas_resize().
It fixes the window resizing of non-elementary applications, since
the elementary window already deals with such resize by calling
ecore_evas_resize.
Using the server_allocation/allocation to determine the resize offset
was not completely precise, and causing the window to not always resize
correctly.
Additionally, calling evas_engine_info_set() on every resize step caused
the window content to blink and resize very slow, because the swap
buffer, swapper, and everything were being destroyed and recreated. Now
only the swapbuf_reconfigure is being called during the resize, which is
way faster.
I add new example related with this. (ecore_evas_extn_socket & plug example)

This avoids blocking in eglSwapBuffers and has the side effect of
avoiding doing unnecessary work - painting where a frame won't be
presented.
We do this by using the event that the wayland compositor will send us
to tell us that the frame has been presented. Due to the fact that
evas_render_updates() could do no work and not cause a eglSwapBuffers we
must always have a frame callback listener setup.

SVN revision: 83387
Before this commit, when using any of the wayland backends, if the user
requested an ecore_evas window of width x height, the reported size of
the window would include the frames width and height.
Now the requested size is stored on the ecore_evas and reported when
ecore_evas_geometry_get() is used, although the ecore_evas is still
created with additional space for the frame area.
This is one of the reasons causing bug #1673.

Implementing support for loadables modules. It makes the engines been
loaded when they are needed. It not breakes the api, so each engine
still has its own api.
The implementation basically is:
* Functions that creates Ecore_Evas, for example
ecore_evas_software_x11_new, request to load its module and then get
the module's function to create the Ecore_Evas.
* The other functions such as \(.*\)_window_get from the Ecore_Evas
its interface and then call the appropriate method.
* As there is no unified interface to communicate with the engines
(not break api problem), all interfaces were declared in
ecore_evas_private.h
* Now the data necessary for each module is not declared in the
Ecore_Evas_Engine structure, instead of this, the struct has a void
pointer that is used by the modules.
* In this first moment engines as software_x11 and gl_x11 were put
together in the same module, but obviously exporting all the things
necessary.
