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....

This changes a lot of things all across the EFL. Previously,
methods tagged @const had both their external prototype and
internal impl generated with const on object, while property
getters only had const on the external API. This is now changed
and it all has const everywhere.
Ref T6859.
Fixes a bug introduce with c8c4572d70.
My guess is that the true intention was to query the Efl.File mixin
first, and the check the specific load_error.
Basically a call to 'efl_file_load_error_get' on an
Efl.Canvas.Image triggered this.
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)
@feature
if its a file downloading (to a tmp location) or a zip/tar/whatever
file being extracted also to a tmp location and that tmp file needs to
be removed after ...you need to keep the obj around to know when to
delete the file. this makes the keeping optional and you query if the
vpath obj is meant to be kept or not. if it's not it's safe to del
immediately.
this cuts down 1 obj per image obj/edje obj when generally unused.
save some mem.
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 fixes evas_object_image_save after changing the orientation
of an image in the GL engine. In SW engine the pixel data is rotated
in memory, so things worked fine from the beginning. In GL we may
have to go through loops and hoops in order to rotate and fetch the
data from the GL texture.
This should fix ce45d44.
Summary:
the canvas image is the only one presenting the load api, in all other
implementations you would only see error messages.

This brings support for the eo api for external buffers (like
the old data_set / data_get). The new API now works with slices
and planes.
The internal code still relies on the old cs.data array for
YUV color conversion. This makes the code a little bit too
complex to my taste.
Tested with expedite for RGBA and YUV 422 601 planar, both
SW and GL engines (x11).
This reverts commit 546ff7bbba.
It seems that eo_del() is useful and removing it was creating bugs.
The issue is that the way we defined parents in eo, both the parent and
the programmer share a reference to the object. When we eo_unref() that
reference as the programmer, eo has no way to know it's this specific
reference we are freeing, and not a general one, so in some
circumstances, for example:
eo_ref(child);
eo_unref(child); // trying to delete here
eo_unref(container); // container is deleted here
eo_unref(child); // child already has 0 refs before this point.
We would have an issue with references and objects being freed too soon
and in general, issue with the references.
Having eo_del() solves that, because this one explicitly unparents if
there is a parent, meaning the reference ownership is explicitly taken
by the programmer.
eo_del() is essentially a convenience function around "check if has
parent, and if so unparent, otherwise, unref". Which should be used when
you want to delete an object although it has a parent, and is equivalent
to eo_unref() when it doesn't have one.
We used to have eo_del() as the mirrored action to eo_add(). No longer,
now you just always eo_unref() to delete an object. This change makes it
so the reference of the parent is shared with the reference the
programmer has. So eo_parent_set(obj, NULL) can free an object, and so
does eo_unref() (even if there is a parent).
This means Eo no longer complains if you have a parent during deletion.
1. unsigned char* as a return type was not even compatible
with the default colorspace (ARGB: 32 bits).
2. Change all unsigned to int for... uh... simplicity
unsigned is more correct than int for things like width,
size or stride, but in fact having both ints (x,y) and unsigned
ints makes the code more complex.
This is a matter of personal taste.
