This has been a long standing plan for improving performance in rendering
vector object. Depending on the test, you will get an improvement between
10 to 35% when rendering vector based object.
We are still maintaining the Cairo backend as the default one at the moment
due to a lack of result comparison tests between the two engine. Hopefully
we should get that covered and we can all enjoy a backend that is 4 times
faster by default.
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 ;)
It has been discussed on the ML (thread: "[RFC] rename efl_self") and
IRC, and has been decided we should rename it to this in order to avoid
confusion with the already established meaning of self which is very
similar to what we were using it for, but didn't have complete overlap.
Kudos to Marcel Hollerbach for initiating the discussion and
fighting for it until he convinced a significant mass. :)
This commit breaks API, and depending on compiler potentially ABI.

I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
Rename a few things:
- draw helper -> efl_draw
- Ector_Rop -> Efl.Gfx.Render_Op
- ECTOR_ bla bla -> DRAW_ bla bla (base pixel ops)
- ector_memfill -> draw_memset32 (and invert arg order to match memset)
The main rasterizer file is now draw.h in static_libs/draw
This is a non functional change, simple code refactor.
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!
@feature
From now on, constructors should return a value, usually the object
being worked on, or NULL (if the constructor failed). This can also
be used for implementing singletons, by just always returning the same
object from the constructor.
This is one of the final steps towards stabilizing Eo.
