Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
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
EAPI is the only solution that worked for MSVC.

Summary:
Implement a class and drawer that outputs image data from the Ector.
Image data is output with a vector object and supports transform.

This will help in the transition from Autotools to Meson. This has been
tested on Windows for which EFL_XXX_BUILD were first introduced.

Alright, so this is a massive patch that is the result of
trying to get rid of unused or poorly implemented classes in
ector. Originally ector was meant to support VG but extend to
things like filters as well. At the moment, ector's design
makes it quite hard to plug in the filters.
For now I think it's easier to implement the GL support for
the filters directly in the engine, where I hope to interfere
as little as possible.
This massive patch keeps only the required minimum to support
a versatile gl buffer that can be mapped, drawn or rendered to (FBO).
It's extremely inefficient as it relies on glReadPixels and lots
of texture uploads, as well as conversions between ARGB and Alpha.
Another type of GL buffer is a wrap around an existing GL image,
but that one is read-only (map or draw: no write map, no FBO).
No, all the filters run fine, and the high-level implementation
(evas_filters.c) does not need to know whether the underlying engine
is SW or GL. One problem though appears with the blending or blurring
of some Alpha buffers, the colors are wrong.
This patch removes more lines than it adds so it must be good ;)

Those Ector APIs are not stable!
|
|
Remove DATA8, DATA16, DATA32
Remove empty data structure
Remove unnecessary typedef
|
|
Ector Surface now inherits from Ector Buffer, and the current
two renderers (SW and Cairo SW) use Ector.Software.Buffer
implementations for pixel surfaces.
Basic pixel handling is merged and will allow easy extension
(color conversion, etc...).
Buffer classes are Mixins to be fully implemented by the final
class, such as: Ector.Software.Buffer, Ector.Software.Surface
or Ector.Cairo.Surface.
This is a large ugly commit. Sorry.
The code is quite a mess right now.

The objective of this patch is to propose a standardized
format for pixel buffers to use within Ector and Evas.
The basic EO API provided here is not meant to be the
fastest path for all operations, simply the most convenient
to generalize. Performance will be achieved by implementing
(or porting) custom draw functions.
This implements support for:
- Generic pixel buffers
- Generic buffer renderer to draw images with ector
- Software engine pixel buffers, ie. malloc buffers
- Software buffer renderer
Cairo support has not been implemented yet.
The only renderer is still extremely limited, as it does not
support Fill modes, Scaling, etc... yet.
Not a single line from this patch has been tested yet.
It compiles. That's pretty damn good for a start!

Depending on the compiler and its version, having twice a
typedef on the same name may lead to a build failure.
Thanks @mythri for the report.
