This is a new function that indicates whether an object is a child of a
parent or not. Dead simple, as this simply compares if parent == this.
Note that this check was impossible to do with the event grabber.
Also, rename group_children_iterate to group_members_iterate for
consistency with the other group_member functions.

Inside emotion, if Eio is compiled, some asynchronous functions are used
and a refcounted struct was used to ensure safety of the code.
Unfortunately the logic didn't make much sense as emotion's private data
is used. The refcount becomes useless, the lifecycle of the data being
bound to the object itself.
Note that an actual crash is almost impossible because:
- eio is actually quite fast
- evas objects are kept alive for 2 frames
- eina_freeq is used to keep eo objects' data alive for some more time
But this in theory fixes the events, as they were sent on the wrong
object. "obj" is the image object, "smartobj" was the emotion object.
This is fixed with a weak ref.
I don't think it is necessary to backport this.
It's not exposing anything that wasn't already accessible before (you
could just add a member and get its clip, for instance).
This will be used by Edje Object.
This is a minor

- color_set
- visible_set
- position_set
- no_render_set
- member_add, member_del
- group_add, group_del
- clip_set
Notes:
- Widget overrides color_set without calling super() which means that
color_get() returns a different value. Also any subsequent child
object add will not inherit the color.
- Smart clipped objects also don't call super.
This patch changes that, but only for smart clipped objects created
through EO. This shouldn't have any side effect.
Introduction to the problem:
- Efl.Canvas.Group has a method member_add() to add sub objects.
- Efl.Canvas.Group (simple smart object) does NOT actually delete the
objects on deletion. But:
- Efl.Canvas.Group.Clipped is a direct subclass and WILL delete the sub
objects on deletion.
Semantically, all smart objects (at least in EO and Elementary) will own
and delete sub objects automatically. Some exceptions are:
- Edje object (smart clipped) does not delete swallowed objects.
Edje object is a "clipped" smart object but it pops out all swallowed
children before getting deleted.
- Evas box/table/grid also pop out their children before deletion.
Those classes are all legacy & internal only.
- Elm.Widget will "manually" delete all its sub objects at deletion, as
it inherits from Efl.Canvas.Group but basically takes full ownership
of the sub objects. Note that member_add shouldn't be used on a
widget, the widgets do it themselves.
Also, smart clipped objects are much more convenient to use as they will
handle some things for you: color, visibility, moving and ownership.
So, the API member_add needs to be marked as own(). But right now
Efl.Canvas.Group does not own. Thus, here's the plan:
- Mark clipped objects as such with an internal API
- Merge clipped smart object features directly inside the standard
smart object.
- Get rid of Efl.Canvas.Group.Clipped entirely and watch all hell break
loose.

This is really only a demonstration of what kind of information
we can print with efl_debug_name_get(). Hopefully this can help
debugging with printf/ERR logs and even help with live debugging
inside gdb.
This shouldn't be used for other purposes than debugging, as the
exact string format is not defined.

When using smart objects (quite likely, isn't it?), the internal
layer usage count was not perfectly tracked. This was especially
true if layer_set() was called on a (top-level) smart object.
As a consequence, there could be no objects in the layer but the
usage would still be > 0. Thus, the layer was not deleted, not
removed from the inlist of layers, and efl_gfx_stack_above_get()
could return NULL as the layer above a certain object was empty.
Fixes T5201
In relative smart move, we only need to check once that the object
is indeed a valid smart object. This drops the call count from ~1.02M

After a long search I found that fileselector was not calling
super.group_del on deletion, leading to the use of dangling pointers.
So let's verify that group_del is properly called.
See T4598
The data class should be specified for debug purposes.
Also, this fixes invalid uses inside the smart object
implementation where it assumed that the smart data was part
of the eo data. It may not (legacy objects).
several calls, specifically evas_object_change_reset,
evas_object_cur_prev, and evas_object_clip_changes_clean that are
called directly or indirectly as part of evas render on at least every
active object if not more, were doing full eo obj lookups when their
calling functions already all had the eo protected data looked up.

of course other things "increase their percentage" as oe overhead now
dropped, and things seem to move around a bit, but it does make sense
to do this with no downsides i can see as we already are accessing the
protected data ptr in the parent func.
evas render in phase1 in order to generate update rects, active,
render etc. object arrays has to walk every object in our tree. this
is a waste of time if we already have walked objects in a previous
frame if they havent changed, so cache this data in render cache in
smart objects to avoid re-walking and now just dumbly "memcpy" these
cached arrays into the master array. i have seen cpu usage by e drop
like about 15% in the sencarios i'm looking at "enlightenment
compositor with some window updating animation all the time, but most
other stuff being static).
@optimize
preparing an object is a good idea. especially with gl. you want to do
texture uploads BEFORE using textures all in one batch. otherwise this
may mean the gl implementation has to make a copy of your data in a
tmp location then copy it in later when texture becomes "unused" as it
may be in use at the moment, or it may have to stall and wait.
i have seen somewhere around 7-10% speedups on nvidia and intel
drivers with this on given a very special test case i brewed up (1000
32x32 images where i change 1 pixel every frame). this should have
impact really when we are modifying textures a lot. this is all i've
implemented for now, but this should/would/could do much more like
re-order map, proxy renders to render FIRST in a pre-render list
instead of inline and to pre-render fbo/buffer content for complex
objects like text or textblock etc.
After a few patches trying to fix clipping of frame or
non-frame objects the icon finally ended up invisible. Even
if the elm_icon was marked as is_frame, its internal evas
object image would not have the flag set, thus it would be
clipped out.
Solution: Propagate the is_frame flag to all smart children,
not only when setting it but also when adding new members.
A hack with the API indicates that the frame edje is a very
special object that does not propagate the flag.

so since this uses new pos - cur pos to move BY x pixels... there is
an issue that if the move of the obj ends up re-moving the current obj
TO the same pos. it moved BY the same delta again thus racing ahead.
not great. because x/y is not stored until the call stack returns to
after the smart move func and the pos set storce the new position in
the object struct. the easiest way atm until we have relative
positioning etc. is to store this in the smart obj and use the delta
at that time of the call then store it immediately so a recursion ends
up with a delta of 0 if its the same pos, so go back to where we were.
this fixes a nasty issue i spotted in fileselector that made filesel
icons race along when scrolling 2x as fast as everything else. oddly i
couldnt see this in any other widget that scrolled when i looked...
which is odd, but... either way a nasty issue... subtle... and now
fixed. never saw this before so this seems new.
Lacking a proper internal tag, I'm using both protected (it is
in fact a protected access function) and beta (to mark as unstable,
not real API).
New smart objects based on EO only should rely on constructor,
finalize and destructor exclusively. In theory, this should be fine.
Unfortunately it may be impossible to inherit from the Efl.Ui.Win
class as it uses a really bad hack and calls super.constructor
inside the finalize method.
This is an override of efl_gfx_size_set. Same as before, the
order of operations matter so it is possible that a corner
case will break. In particular, legacy code was:
- intercept
- smart resize (do stuff), super, super, super
- evas object resize
The new code is more like:
- intercept
- super, super, super, evas object resize
- do stuff
But unfortunately this broke elm_widget (read: all widgets) as
the internal resize was done before the object resize. So,
inside the resize event cb, the resize_obj size would not match
the smart object size. >_<
This is an override of efl_gfx_position_set.
As for the other patches, I hope I didn't break anything.
A problem likely to happen is that the super call was inserted
too early or too late in the call flow. For instance:
_myclass_position_set(obj, x, y) {
position_set(super(obj), x, y);
position_get(obj, &prevx, &prevy);
do_something_with_delta_xy();
}
The above code flow is obvisouly wrong, but may have crept in this
patch (such a bug sneaked in inside smart object, breaking
everything at first).
While this kind of API seems to make sense with smart objects
(relative coordinates), it is currently not used apart from
the smart object class itself.
So, for now, I'm moving this to legacy to clean up Efl.Canvas.Group
and we can later add the equivalent in a clean "group" API.
These should be just overrides of Efl.Gfx.visible.set. Many
widgets were handling smart show() and hide() manually, which
means this patch is quite large.
Hopefully this doesn't break anything, obviously. But here are
some widgets known to be problematic, as the old code flow was
really strange (sometimes not calling the efl_super function):
- window
- notify
Similarly to group_color_set, group_clip_[un]set should not
exist and should be a result of efl_super and inheritance.
This patch also removes clip_unset from the EO API and keeps
only clip_set(NULL). The reason is that it will avoid bad overrides
of clip_unset() vs. clip_unset(NULL). This also simplifies the code
a bit. Ideally we should be able to reintroduce clip_unset in EO
if we can have a "@final" tag (like java's final keyword), to
prevent overrides.
Widgets should simply override efl_gfx_color_set and call
super all the way up to evas object.
Legacy compatibility with call interceptors and early call
abortion (eg. delete_me or obj->layer == NULL) are implemented
with an internal call. See the previous commit introducing the
API.
Most of the smart functions "Efl.Canvas.Group.group_xxx" should
not exist and be overrides of the base object function instead.
Cleaning this up is necessary if we want an EO API for custom
smart objects. This patch is the first attempt at removing a
method (the simplest one).
As for no_render, I wonder if propagating to the children
really is necessary. evas_render should skip them already.
There were 2 wrong conditions.
1. visible check.
Smart changed can be skipped only if previous/current visibility are false.
2. clipper.
Actually, it needed to check previous/current clippers but previously,
it checked only previous clippers.
