Dumb implementation of a "smart" buffer capable of wrapping an
RGBA_Image but that can still be rendered on screen (ie, an
Evas_GL_Image is attached to it).
This fixes crashes, adds safety, and notes a couple of things that
are not yet implemented:
- Make an Evas_GL_Image from an RGBA_Image so we can draw it on the
canvas. This means Evas.Ector.GL.RGBA_Image.Buffer
- Readable Evas_GL_Image objects with gl_read_pixels
--> Implement proper map() & unmap() for GL buffers
This is a major refactoring of the evas filters submodule.
Use Ector.Buffer and the map/unmap methods instead of directly
accessing image buffers with RGBA_Image. RGBA_Image is still
used under the hood, for two reasons:
- Required for the final output (blend onto Evas itself)
- Required for the scaling routines
FIXME:
- Breaks proxy support (ie. all kind of texturing).
- This breaks filters support for the GL engine.
Since Evas still relies entirely on Image_Entry and Evas_GL_Image,
we will need an engine-specific wrapper object creating a Buffer
around an existing cached image.
Currently only SW support is implemented. GL will be more fun to
do (with glReadPixels and whatnot).
Summary:
'cached' flag is not enough to check whethere data is loaded and texture is uploaded.
so check more options for prevent re-preload image data on gl-backend.

Summary:
When preload is cancelled before finishing loading,
should reload the image data and update the texture during rendering object.
So, force texture to be updated on first drawing time.
(It should be guaranteed that preload image object is hidden before preload done.)

The original plan was to have two different surfaces for GL and SW,
but this is probably not going to happen anytime soon. So, move
the implementation back to lib/ector. This avoid a file duplication.
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.
This rely on a faster code path to upload dynamic texture. Once we get support
for gbm, we should see significant performance improvement in speed, but this
first step is already a 5 times improvement (Ok, we get from really bad, to not
really useful...).
egl images created using tbm surface for native surface set use
GL_TEXTURE_EXTERNAL_OES as texture target, so we should bind to
this target when rendering.
Dynamic hint set using tbm surface also creates egl images, but
as we only use RGB* colorspace for this we can use GL_TEXTURE_2D.
So, keep track of texture target in shader array, and bind to the
appropriate one.
This also fixes the bug that image_data_get only worked when BOTH
sec_image_map and sec_tbm_surface extensions are supported.
Summary:
Evas GL maintains internal resource (XWindow, EGL Window Surface, EGL Context)
per thread to be used for make current when indirect rendering is used.
Currently this internal resource is created regardless of current rendering mode,
and always created when a new Evas GL thread is created by the application.
Internal resource created in a new thread is not freed until evas shuts down
in the main thread, so this causes memory/fd leak.
This can be fixed by creating internal resource only in necessary cases (ie. indirect rendering),
and adding tls resource destructor to be called when thread exits.
- image_file_colorspace_get
This will be used to determine the best loading format, especially
targeted at edje_cc / edje_decc so we can avoid ETC re-encoding.
- image_data_has
Checks whether the image is currently loaded in (CPU) memory,
and also returns the current colorspace.
After clip_image_get, the old mask may be replaced by a new one,
and unref'ed, but it is later on set back as the context mask image.
Maybe it's possible that there was 0 reference and the image
got freed in between.
No idea how to test this.
@fix
Okay, I'm being paranoid and this can't possibly happen (calloc
fail? yeaaaah) but this makes sure we don't return NULL after
freeing the original image.
Summary:
When Evas GL apis are called outside of on pixels callback,
evas gl backend context may have been made current, and Evas GL will
render into a wrong context.
So here we provide context restore mechanism of keeping track of
currently bound context and calling make current when needed.

Before this patch, those EGL/EvasGL functions can not work
without a current context. But EGL does not require any
current context for those to work, or at least, this should
be left to the driver to decide.
Evas GL was only able to get a pointer to the display
if a context was current.
The display pointer should be infered from Evas_GL unless
we can find a current display. EGL does not require a
context to be current in most of these function calls.
This should bring evasgl a little bit closer to EGL in terms
of behaviour (those are EGL-only extensions, btw).
Thanks @spacegrapher for the quick review
@fix
When glClear is called in direct rendering move (DR), we usually
have to skip the call altogether because clearing out transparency
would erase the pixels in the evas backbuffer. This means Evas
would not be able to blend an RGBA GLView on top of other objects.
But COPY mode should allow Evas GL to poke holes in a window
backbuffer.
Thanks @spacegrapher for the review :)
NOTE: Elm GLView also needs to pass the render op to its Evas.Image.
@fix
evas_gl_native_context_get is an internal function
passed around from an evas engine to evas_gl so that we can
implement evasglCreateImageForContext without exposing
any evas engine internal structure to evas_gl.
It's all a ittle bit ugly but the previous solution with
dlsym(DEFAULT) didn't work.
Those two functions were doing exactly the same thing[1], which
is free an image, so this commit only attempts to simplify the code
a little bit.
[1] Actually image_map_surface_free() might even not have worked
properly with cserve2 sw (calling unload instead of close).
Summary:
When evas is recreated, this static variable value remains,
so it references already freed memory.

Summary:
Evas GL now supports surfaceless make current, where
evas_gl_make_current can be called with sfc parameter NULL.
This closely resembles EGL_KHR_surfaceless_context extension,
where applications that only want to render to client API targets
can make current to NULL surface instead of creating a dummy egl surface.

Summary:
Now we can support EVAS_GL_GLES_1_X version for GLX backend
with both direct and indirect rendering.
Refactored api get functions to have similar code path for each version.

Thanks Dongyeon for finding out this solution. Now that was
one nasty bug :)
Somehow the currently bound texture id would not match what
Evas expected, so Evas would not call glBindTexture when
required. As a result it was drawing black (sampling from tex 0).

Use fourth component texture. Update mechanism generation pixels, scene renderer
to texture and geting color pixels from texture. Update shader for color pick.

EGL might very well not support RGBA read mode, so we
need to check for it first.
Also remove some error logs (see previous commit), and useless
initialization of the Evas GL engine.
@fix
Summary:
Used engine function for load image/data and use texture unit through
Evas_GL_Image object
Used Evas_ColorSpace format instead Evas_3D_Color/Pixel format
Added transformation matrix for adjusting texture unit coordinates in shader
Added property in Evas_3D_Texture for mark possibility get texture without atlas
(see https://phab.enlightenment.org/conpherence/54/, I suppose it will done
after this patch)
