Summary:
Current preloading is too buggy since it's on thread-based.
This is a fundamental improvement to fix a bug.
The critical issue here is,
When preloading img object suddenly cancel its preloading,
the object possibly cannot render image next then because
renderer doesn't have any idea when async cancelling is
finished. Renderer just tries to render regardless of
image loading status, and this could occur no-texture(in gl case)
image object.
So, here improvement is, adding a notification for async cancelled
so that putting img objects to redraw images properly after their preloading is
cancelled.
The best scenario to reproduce this bug is this one.
Evas_Object *img2 = evas_object_image_filled_add(evas);
evas_object_image_file_set(img2, "test.jpg", NULL);
evas_object_image_preload(img2, EINA_FALSE);
evas_object_resize(img2, 200, 200);
evas_object_show(img2);
Evas_Object *img = evas_object_image_filled_add(evas);
evas_object_image_file_set(img, "test.jpg", NULL);
evas_object_image_preload(img, EINA_FALSE);
evas_object_move(img, 200, 200);
evas_object_resize(img, 200, 200);
evas_object_show(img);
evas_object_image_preload(img2, EINA_TRUE);
If you run this on gl backend, occasionally happens rendering fail.
Yet there other bugs on preloading feature....

Summary:
Prerequisite: Partial rendering ON + Image Prealoding + Triple surface buffer of GL.
Previously, evas trys to draw of an image which didn't prepare of image data yet (in case of preloading)
This time, it will draw a solid color onto the dest sufrace 1,
But luckily, preloading is finished just after, it draws proper image data onto next surface 2 and 3.
Now, triple buffer is filled with the image data but only first frame is still empty. That's a problem.
This patch skips to draw image if it doesn't prepare data yet, but once the preloading is finished,
it starts to draw images.

evas_object_image_data_get() is a legacy API that I made work
with snapshot objects (evas_object_image_snapshot_set()). Some
changes in the engine broke the behaviour and this patch fixes
it.
When getting the pixels from an FBO, in read-only mode, we need
to create a temporary image (pixels surface) that contains the
copy of the pixels we get from glReadPixels. This image needs
to be deleted afterwards. It is thus stored by the image object
and freed upon _image_data_set() (good) or object deletion (bad).
FBO + read-write is not supported by this API (it is supported
through buffer_map as the filters had to use that).
Fixes T5754
Add functions for assigning hardware planes to evas image objects.
The unfortunate asymmetry of the code is due to plane assignment being
only fully verifiable by doing a test commit through ecore_drm2, so it's
simpler to have the "test" function also do the "assignment", and call
the release on failure to clean up after a failed test.
If an evas object is a wayland dmabuf, uses native surface 5 or higher,
and has a scanout handler set, then it meets the basic requirements for
placing on a hardware plane.
Following a remark in the mailing list, it is pretty clear that
Efl.Gfx.View.view_size is not as simple as "image_size".
I have defined this new image_size as being the size of the
image file, and not what's currently loaded. So it will not
apply to proxies, gl views, 3d scenes, etc... but only to
standard image files loaded with file_set or mmap_set.
Supported objects:
- Efl.Canvas.Image (evas image)
- Efl.Ui.Image (elm image)
- Elm.Photocam (note: still needs some interface work)

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).
This make save() work on snapshot objects, provided the call
is done from inside render_post.
Also, this saves the filtered output of an image, rather than
its source pixels. Any call to save() on a filtered image must
be done from post-render as well.

to date if you use async preload we still load the header
synchronously and this can be horrible especially with generic
loaders. there is no way to farm this off to the preload thread. now
there is. youhave to set it as a skip head load option before doing a
file_set AND you need to issue a preload ... but now it's possible.
@feature
This reverts commit 4e110a34bf.
Urgh. I'm stupid. Conceptually I still like the idea of the
region proxy, that only renders part of the source object
in a proxy surface. The problem right now is that the proxy
subrender mechanism renders to a surface that belongs to
the **source** and not the proxy object. As a consequence,
the region would become a property of the source, rather than
the proxy, which is not at all the intention of the original
patch. In other words, everything would fall apart if an object
has more than one proxy, for whatever reason.
I realized that when trying to actually test the region proxy.
It didn't work at all. Revert for now.
This will allow partially rendering a proxy in a smaller image,
limited to the specified region. At the moment, this will allow
apps to create proxies of very large objects and let them deal
with the geometry & clipping.
This is not directly solving the issues with adding a filter
to textblock or the infinite page scrollers.
@feature
this is how you would possibly use prepare stages for objects like
image objects by pre-rendering them to a buffer. this is not complete
and it's actually disabled right now, but it's to show how it might be
done. some more exploring is needed, but this is to share how it
might/should work.
Efl.Flip is now the enum, the interface is Flipable.
We could even use names like Efl.IFlip a la Java.
eo_prefix is used to have pretty names in C. legacy: null
is removed from the enums. orient_x0 is removed and only
defined in C with #define
Summary:
Added flip and orientation interface and used them in evas_image.
Removed efl_image_orientation_set API and used efl_orientation_set and efl_flip_set API.
In implementation part, converted enums back and forth in order to keep current implementation as it is.

There's no point in calling fill_set AND fillet_set(false).
If a users wants to specify the fill, that should be enough
to switch to non-filled mode.
Maybe the "filled" mode should even be called auto or something?
This replaces standard Evas_Object_Image when it is used "normally",
ie. it's an image from a file or from a pixel buffer. All other APIs
(proxy, snapshot, 3d, gl, ...) are disabled on this object.
Also, reduce number of failing calls when the object is not a legacy
object, but a legacy function is called. This is because a lot of
image APIs are called internally using the legacy APIs, often in
order to reset the state of the image object (eg. set file to NULL,
etc...)
Efl.Canvas.Snapshot and Efl.Canvas.Proxy are specialized
classes previously implemented as features of Evas.Image.
Note: this half of the work, as I suffered from a bad
merge and rebase with my work branch on top of master.
