Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is from a series of patches to rename EAPI symbols to
specific library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`.
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
LIBAPI is the only solution that works for MSVC.

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.
(#0) evas_cache_image_drop (im=0x0)

(#2) efl_destructor
(#3) _efl_del_internal

Currently, edje.pc gets its lua Requires from the -Dlua-interpreter argument.
If -Dlua-interpreter=lua, an unversioned lua entry ends up in Requires, which
cannot always be satisifed. The evas filters meson.build handles this case by
generating a version-specific entry. This patch copies that logic into the top
level meson.build, and passes the result to the edje subproject.

Summary:
If an input buffer and an output buffer for the curve filter are same, it reads
and writes to the same texture which behavior is not defined. I could not find
good reference for this, but following could be a reference.
https://stackoverflow.com/questions/11410292/opengl-read-and-write-to-the-same-texture
The texture gets 0 color value as a result. So the curve filter does not work.
This patch makes the curve filter use different input and output buffer.
Test Plan:
This attached file could explain what 'read and write to the same texture' is.

When you run filter examples with enabling GL engine support,

So, efl_unref has to be replaced with efl_del.

meson was taken because it went quite good for enlightenment, and is a traction gaining system that is also used by other mayor projects. Additionally, the DSL that is defined my meson makes the configuration of the builds a lot easier to read.
Further informations can be gathered from the README.meson
Right now, bindings & windows support are missing.
It is highly recommented to use meson 0.48 due to optimizations in meson
that reduced the time the meson call would need.

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 might not be used as over two consecutive runs all the
same buffers should be used. But it could happen if some
parameters in the filter change (eg. blur radius).
Fixes major (GPU) memory leaks. Reuse mode is still leaking.
An odd-sized image scaled down by 2 was losing 1 pixel during the
downscale, and it was not restored after scaling up. The same
happened with downscaling by 4 except the effect was even more
visible.
This meant that a moving snapshot with a large blur would trigger
some really ugly sampling issues if the content below was precise
(such a text).
This dramatically improves the performance and now seems
to give acceptable results. Eventually we need a quality flag
in order to enable this or not. Alternatively, "gaussian" blur
mode would skip this optimization, while "default" would trigger
it.
When the filtered object is an image, without borders, map,
fill info or anything of this sort, then the filter input
buffer is really just a copy of the original image. We can
skip that to save on memory usage and pixel fetches.
This was a poor attempt at improving the performance but
obviously the root cause isn't fixed (too many texel fetches).
Uniform should (theoretically) work better than an attribute
the for loop. Just a guess here.
This also makes GL blur use a float value as radius, allowing
future extension to non-integer blur radii, as well as using
linear scaling as a fast blur approximation.
This will reuse existing buffers by resetting only the minimum
required in the filter context (also reused). Work in progress,
as the actual reuse is disabled for now.
This avoids creating one more FBO and doing one more draw,
by rendering the image input data directly into the input
buffer. This also makes the code common between SW and GL.
