Summary:
During shutdown we used to call engine_image_free() which was causing some deadlock.
as we have evas_cache which takes care of freeing all the images we just have to
delete the generic cache without freeing the image during shutdown.

Since we moved to floating calculation for msaa, this comparsion
is not working for direct image drawing though it's doable.
To resolve this, we can compare floatings regardless of msaa enable.
Summary:
If image object geometry is same with image size, then a crash occurs on both
GL and SW engine.
[Test Code]
evas_object_image_size_get(img, &w, &h);
evas_object_resize(img, w, h);
[GL engine]
eng_ector_buffer_wrap should use output instead of engine for calling
evas_ector_buffer_engine_image, because it expects the output not the engine.
[SW engine]
eng_ector_buffer_wrap should check if im->image.data is NULL because
_evas_ector_software_buffer_evas_ector_buffer_engine_image_set returns before
calling evas_cache_iamge_ref if im->image.data is NULL, and it causes
a segmentation fault finally with following backtrace.

While we render vector drawing on ector,it uses ector buffers for subsequent compositions.
In this sequence, it switches ector buffer with a composition target,
while resuing the global ector context.
Previously, it trickly switched ector buffer, it broke the ector begin/end pair.
Now, it needs to recover global ector buffer once the composition finished.
Thus ector buffer need to return the current pixels information for this.
Summary: This is the first version of inverse color filter both GL and SW.
Test Plan:
1. Create filter_example with following .
efl_gfx_filter_program_set(image, "inverse_color ()", "inverse color");
2. Run.
./filter_example (Use ELM_ACCEL=gl for GL engine)

For reducing maintainability burden,
We drop supporting cairo backend.
The default backend is to software implementation from now.
It's well maintained so far and works good.x
Summary:
in gl engines, orientation is applied during the draw. this is different from
sw engines where the orientation is directly applied to the internal pixel data
which results in a state change of the object internals.
this preserves image cache state and allows the image to be loaded normally instead
of displaying a black rectangle if orientation is set prior to a texture being
created

evas_gl_common_image_content_hint_set makes RGBA_Image NULL if content hint

efl_file_save(_efl_canvas_image_internal_efl_file_save_save) does not work
in this case because ENFN->image_data_direct_get returns FALSE.
This patch makes ENFN->image_data_direct_get work but you need to free its

Summary:
GL engine has used integer coordinates system since it's born though
OpenGL basically uses floating point vertex coordinates system.
There were many dissatisfaction, complaints about this
since object's transition is jiggled, not perfectly smooth.
It's obvious because Positioning must be stepping with integer units
without any subpixel rendering.
Our gl engine currently supports msaa options and evas map allows to
have double precivion coordinates system, our engine must do handle this over as well,
to work together.
If you don't like change,
We could switch behaviors optionally (turn on, only when msaa is enabled)
But I think it's pointless using integer coordinates system in GL thesedays.
It just make code complex to maintain.
There will be an additional patch coming for SW backend map behavior soon.

This implementation uses Ector_Buffer to generate mask image from vg container,
and pass it to Ector engine. Ector renderer could blend this image as a mask.
Yet only vg container works as a mask, we could extend shape to support masking later.
Still vector gl drawing is not completed, We use software ector buffer to draw on it.
This is on progessing.
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:
Adding cache targets in other modules are inproper.
This can't be managed by cache module inside.
One representive scenario is,
when preload cancel is triggered, preload canceling sequence
can't be performed properly because cache targets implicitly were
increased by backend modules.
And then, Cache itself couldn't get notified it.
see this condition.
if ((!ie->targets) && (ie->preload) && (!ie->flags.pending))
in _evas_cache_image_entry_preload_remove()
Consequently, I move preloaded callbacks to sync with adding cache targets,
not to add by backed engines themselves.
This will bring Cache to manage cache targets properly.

If the image has no data, it may get an allocated surface of 1x1 but it
is not sane to return the pointer to that data, as the user would expect
a normally sized image (in my case, 1920x1080).
I do not fully understand what is going on with this image. But at least
this transforms a crash into a simple ERR in ~/.xessions-errors
Two similar crashes happened:
- SIGSEGV by writing data outside of the image data
- abort() in free() because the malloc metadata has been overridden
when writing outside of the image data (newly allocated 1x1).
Fixes T5957
@fix
gl_generic_context_find() returns the gl shared context struct but
this is not just a read-only operation. It in turn calls window_use
which may call make_current. This can invalidate the work of evas gl
when the API tried to switch to a specific context.
This fixes evas gl with multiple outputs.
