this adds a lock for when walking all the objects to generate render
commands for an async render. this allows even the object tree walk
plus update area caluclation to be moved off into async if every oject
that can change canvas state actually does so correctly. this change
adds all those lock block calls to synchronise with an async object
tree walk.
Thanks cedric for the report.
We'll need a new function (after 1.12) to detect if the current
cow pointer is the default data or not. Maybe eina_cow_default_get()
or maybe something just returning a bool.
As pointed out by Cedric, the memory usage of basic evas objects
has increased a lot in recent versions of EFL, in part due
to this excessive use of filters data.
This is a partial fix for ticket 1725.
Before this change eo_add() used to create an object with 1 ref, and if
the object had a parent, a second ref.
Now, eo_add() always returns an object with 1 ref, and eo_add_ref()
preserves the old behaviour (for bindings).
eo_unref now un-parents if refcount is 0, and eo_del() is an alias for
eo_unref (will change to be a way to ensure an object is dead and goes
to zombie-land even if still refed).
the text object walked all text items and took the biggest. when that
big item used some fallback font that didnt match the primary font in
ascent/descent etc. things went wrong - text expanded when not
expected to. this makes text objects just use the primary font
ascent/descent metrics and fixes e titlebar magically expanding thus
compressing window content when not expected.
We couldn't do evas_object_color_set() on a filtered text
object simply because the color was not properly taken into
account.
This should simplify some effects as it'll be much easier to
set a color or alpha value to the text regardless of the filter.
Hmm, is this a fix or feature? O_o
Summary:
text_props.len indicates visual length from harfbuzz logic when it is available.
But, input pram "idx" is logical length. So, ellipsis works abnormally in some case.

This adds filter support to Image objects as well.
The exact same filters can run on Text and on Images
(provided some colorspace limitations are respected).
This basically adds:
- Support for RGBA input buffer
- Eo entry points for Image filter support
- Implement basic filter support in Evas_Image
Summary:
When the text was shorten by ellipsis, object size was fit to the text width.
If new text was set to the object, the text calculated with the smaller size.
It made shorten the object size when the text is set repeatly.
If the text is cutted off with ellipsis, it means there is no need to
resize the object.
Test Plan: elementary_test -> FileSelector Entry -> Click "Toggle Folder Only mode" button repeatly.

This will inform the client whether an asynchronous filter properly
rendered or not.
I actually don't know any case where rendering can fail at runtime.
If the filters fail to render at runtime (that is, parsing went fine
but a command failed to run properly), fallback to normal rendering.
This should prevent text from disappearing when using proxies and
the OpenGL engine (for now).
If a text object changes regularily, there might be cases where
the object will be rendered as a simple black rectangle for just
one frame.
It seems that the previous output buffer is deleted before being
actually rendered on screen. This patch will delay the deletion
of the previous buffer until the current one has been rendered
to the target surface.
And again, thanks zmike for reporting.

Also, remove globals A, R, G, B from parser.c... these are
temp variables used in a macro.
My CFLAGS didn't include -Wshadow so I missed those.
Thanks Tom for spotting :)
If source_set was called after program_set, then parsing would fail.
It used to work because the program was re-parsed at source_set.
Now, save the code, mark the filter as changed, and reparse again
if the source changed (keep track of invalid programs to avoid
excessive parsing).
Proxy sources & objects were not properly unset.
This results either in crashes (especially in the Edje tests)
or dangling objects with tons of references.
Remove the refcount increase/decrease, as it is redundant.
Store pairs proxy+source instead of just the source in all hashes,
so we can unset the is_proxy flag on the proxy when there are no
sources anymore.
This patch implements the final draw from RGBA_Image to the
OpenGL surface. We can even steal the output buffer and
redraw it quickly, without having to re-render everything
(same as in SW).
Since the filters will have to decide on which engine (SW, GL) to
choose from to render the font and the effects, move the font
draw call inside the filters module.
Quick and dirty solution to support the OpenGL engine:
[1] Allocate CPU buffers
[2] Render text and process all effects to these buffers
[3] Push final image as an OpenGL texture.
This patch implements [1].
This is the first possible optimization: save the rendered
text (since we already have the output buffer anyways), and
reuse it if the text + filter didn't change.
