so i was just about to add buffer age debugging evlogs to everywhere
doing buffer age and i found... drm gl and wayland gl engines DONT
HANDLE age change like gl_x11! they dont reset to a "full render" for
that frame. well well. this explains bugs i am seeing for sure. very
very bag! i thought this was handled properly. this does lend some
credence to my thoughts about somehow having a single universal buffer
swapping/update calculating and "applying" api inside efl somewhere...
anyway - this fixes this issue for these 2 engines which is a real
necessary fix to be correct.

The first patch did not work for maps. This explains why the
original code was so weird. But it actually made sense.
After struggling a bit I realized that we really just need
to shuffle around the pixel position on the window to map that
of the position in the canvas (unrotate it).
Note that compatibility with GLSL-ES (for OpenGL ES) implies
we can not use an array initializer like:
vec2 pos[4] = vec2[4](a,b,c,d);
So the code could probably be optimized. But at least this works.
This patch also avoids calling glGetUniformLocation again and
again.
as per mailing list discussion about dropping xcb support now. it
hasn't been complete for a long time, thus not recommented for being
turned on. as we are moving to a wayland world xcbmakes even less
sense. as agreed, time to clean up a bit and remove a distraction as
well as not well tested code. this also updates po's too.
@feature
The original solution was really complex and relied on
transforming the current gl_Position into the screen
coordinate in pixels, and map that to the pixel position
in the mask.
This new solution simply pushes the required vertices for
the mask, based on its geometry. This fixes masks when used
in a rotated window.
Why was it so hard to get right? :(
@fix
draw_frame is a legacy feature that draws a very ugly window border
with a white rect and a black text as title bar. This could be
used in wayland when using only the ecore_evas APIs, rather than
elm_win.
Note that the API ecore_evas_draw_frame_set() can not possibly work
as the flag is checked when the ecore_evas is created, so changing
the flag has no effect on existing windows.
Finally bring these together as much as possible to avoid future
diversions when bugs are only fixed in one or the other.
There are functional changes - state tracking for client side effects is
now added to the shm engine, some bug fixes for the egl engine have been
brought to the shm engine.
Brings resize code into the common implementation - there is a functional
change. There appears to have been a bug in the egl resize where it
used the same w, h order for portrait evases as for landscape. This was
fixed in shm. I've used the shm variant for the common code.
Moves transparent set into the common implementation - there is a
functional change here - the egl engine now calls transparent_set in
render_updates like the shm engine.
It is probable the this was the intended behaviour all along.
Moves alpha set into the common implementation - there is a functional
change here - the egl engine now calls alpha_do in render_updates like
the shm engine.
It is probable that this was the intended behaviour all along.
These engines are incredibly similar - by sharing the same engine info
structure we'll be able to simplify the wayland ecore_evas bits and
make them much more maintainable.
So when mouse / keyboard are present or not it will
generate events.
ecore_evas/wayland will handle that creating or
deleting evas devices for each one (seat device
will be used as parent).
Create or delete evas_devices with class EVAS_DEVICE_CLASS_SEAT
for seats on each ecore_evas created so far.
Initially it's named considering its Wayland id.
there are spu apis to turn subtitles on and off and this should be off
until turned on by api. you really have to be able to choose the
subtitles to display - eg language etc. to use them effectively.
this fixes T4795

In the event that an ecore_evas (using wayland_shm) gets hidden then
the corresponding wl_surface gets destroyed. If evas_norender is
called after that, the outbuf_redraws_clear function follows.
Outbuf_redraw_clear function ends up trying to post updates to the
wl_surface however if that wl_surface is gone, then we end up crashing.
This patch addresses that issue by checking for a valid wl_surface
inside the engine before trying to post updates to that wl_surface.

Now that we have redraws_clear exposed through software generic, we can
use that to do the final buffer swap from the main thread instead of doing
it in outbuf_flush which runs from the render thread.
This becomes more important later when other call sites in the main thread
will perform buffer flips.

When triple buffering it's possible that we'll only need two buffers at
a time for long durations. When we finally call upon a third buffer it
hasn't been used recently enough to do a partial redraw.
By picking the oldest available buffer when multiple buffers are free we
can increase the likelihood of doing partial redraws.

One deadlock and one segfault.
Patch 1:
Software X11 Evas Engine: Fix deadlock
Summary:
The patch bc6e8d2692 introduced a callback responsible to notify the pixels
that were sent to the X server. Since all EFL rendering is done by another
thread, the callback should be called from the main thread context.
To achieve this behaviour evas_software_x11_region_push_hook_call()
was using ecore_thread_main_loop_begin(), which may cause deadlocks, since
evas mainloop waits for the render thread and the render thread waits
the mainloop.
In order to fix this problem, the function
ecore_main_loop_thread_safe_call_async() will be used to
schedule the callback to run in the main loop context.
Since a callback is schedule to run in async manner, the pixels that
were sent to the X server must not be deleted until the user is informed.
In order to avoid more mallocs(), this patch adds the support for refcounts to the
X_Output_Buffer and Xcb_Output_Buffer.
Patch 2:
Ecore_Evas VNC: Use the image size to create the buffer.
In same cases they may differ and may lead to a segfault, since
memcpy() causes a buffer overrun.

KHR partial damage must be set once at the beginning of rendering with
buffer damage for the entire scene to be rendered. Doing otherwise can
result in graphical anomalies on some GL implementations.
There's no reason why we'd need a full redraw if the buffer age for
this buffer isn't the same as the buffer age for the last buffer, so
let's cut out this thing.
