It's a complex struct but defined in EO as a simple struct. ABI-wise
it's equivalent to Eina_Rectangle. Some macros that use Eina_Rectangle
also work on Eina_Rect out of the box, most of the code dealing with
x,y,w,h will require no modifications either.
But Eina_Rect provides direct access to a size or position 2d component,
as well as the usual x,y,w,h. The field "rect" is provided as a
convenience for code dealing with both Eina_Rectangle and Eina_Rect. We
may or may not require it.
Note: Size2D could use unsigned values but I have spotted a few places
in the code that actually use -1 to indicate invalid size (as opposed to
0x0).

This is the first step toward handling multi output. This patch
remove engine.data.output from Evas structure and use an Eina_List
for it instead. It also start moving code around to fetch an output
or an engine context (which are the same at the moment, but will be
split in a later patch).
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.
tha's silly and just adds overhead we don't need. my test dropped
_eo_obj_pointer_get overhead in perf profiles from 4.48% to 2.65%. see:

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.
I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
This rely on a faster code path to upload dynamic texture. Once we get support
for gbm, we should see significant performance improvement in speed, but this
first step is already a 5 times improvement (Ok, we get from really bad, to not
really useful...).
Async rendering doesn't have a main loop cleanup function. The only one
being called is in the rendering thread. I wrongly assumed in my previous
patch that render_post on an object was called after the async render was
done which is obviously not the case as pointed by Subhransu. This patch
now wait for the async rendering to be done.
Summary:
As we always call evas_object_inject in every Evas Object's ctcor,
it seems sensible to move this repeated bit of code to the super
(Evas.Object).

From now on, constructors should return a value, usually the object
being worked on, or NULL (if the constructor failed). This can also
be used for implementing singletons, by just always returning the same
object from the constructor.
This is one of the final steps towards stabilizing Eo.
