Automatically fallback to OpenGL ES 2.0 if OpenGL ES 3 is not supported.
This is a first step in trying to support GLES 3 for Evas GL.
This commit is also a wild test to see whether using GLES 3 contexts
by default will break anything. The theory says that GLES 3 is
backwards compatible with GLESv2.
So, if anything GL breaks for you... scream loudly!
But before reporting any bugs, please set the env variable:
- export EVAS_GL_DISABLE_GLES3=1
This does not add any requirement for GLESv3 support.
This requires a special context that matches the configuration
required for GLES 1.1. Otherwise eglMakeCurrent() would fail
miserably with EGL_BAD_MATCH in case of indirect rendering
(at least on some drivers).
Summary: If eglGetError sequencially called, second eglGetError() doesn't give the information of real Error.

The exact same ugly macro would appear hundreds of times in the GL
code:
GLERR(__FUNCTION__, __FILE__, __LINE__, "");
Instead, override the common GL functions iif GL_ERRORS is defined.
This greatly simplifies code and removes tons of useless lines.
Also, this will give better debugging output as the exact code line
is printed, and the function name is also printed.
Also, fix linking to the glerr function.
This is a code cleanup. Hopefully I didn't break anything with this
big operation of find & replace.
Summary:
This native surface type is based on the tbm surface used for the tizen platform.
EGL_TIZEN_image_native_surface EGL extension is used to map
tbm surface to an egl image

Summary:
Without EGL_PLATFORM environment variable, eglInitialize() can be
failed because egl tried to load DRM platform instead of X11 platform and it
tried to handle XDisplay pointer as a gbm_device pointer as well.
The failure seems to be occured especially if the egl was built
with DRM platform as native platform.
This revision can prevent the failure by indicating proper egl platform using
EGL_PLATFORM environment variable.

If MSAA was requested, it is very likely that no config was
found (depending on the driver), so we'll try again without
MSAA. Yeah, this might not look very smooth but it should be
better that failing at eglMakeCurrent.
Carefully select the requested EGL config and match it with
the available visual from X, including the following options:
- Stencil
- Depth
- MSAA
TODO: The same thing for GLX. And fix direct rendering as well.
this cleans oyt a few bits o9f old glx context handling code that are
no longer used as well as avoids causing server-side to crash on
tryng to set a "none" glxwindow as current. this is what cases the
nvidia server-side crashes.
Summary: glsym_evas_gl_common_error_set used here leads to an implicit
declaration in compiler warnings. Remove the call to that function and
just print out an error message. This is a cleanup function anyway.

Summary: In fixing a Coverity issue, I copy/pasted a call to
evas_gl_common_error_set without compiling :( Bad me !! This commit
fixes the issue (data was undefined). Since evas_gl_common_error_set can
take NULL as the data parameter, lets use that.

evas gl window was freed before new one was created getting shared ctx
to 0 refcount thus freeing everything there - BAD. fix. new issue in
git, not from release
so this is a re-try at the evas gl destination alpha fix. this is what
cedric tried, but done RIGHT. it required adding an ecore_x call to
create a window with correct visual/colormap. it requires doing
visuals totally correctly all the way from ecore_evas to the evas
gl_x11 core. nvidia drivers are very picky about visuals. i also had
to vid the egl/gles code too to do the same thing. nvidia gles/egl
drivers are also picky, mesa is not. this all requires a lot of code
changes. it's far from trivial
this isn't backported for a few reasons:
1. verify this fix doesn't break for anyone.
i tested:
nvidia glx + egl/gles
intel glx + egl/gles
radeon glx
it needs wider testing. nouveau, fglrx for starters and maybe
some other gles/egl drivers.
2. have some review time
3. time to settle before blasting to stable branches
@fix
Not sure if this is very relevant, since GLX does not support
GL-ES as such, anyways... We should be using the extension
GLX_EXT_create_context_es_profile to create proper contexts.
Note: GLX + OpenGL-ES 1.1 crashes at any function call on my
machine (binary bloc driver), while EGL + GLES1.1 is fine.
Forgot to set the TLS value after creating a new context.
No problem would show up in most cases, even in my test app.
But elementary_test GLView would just not work at all, spitting
incomplete FBO errors at me. Damn this one line was hard to find.
But introduced in df66916cd22ec6c4.
This introduces XPixmap usage for indirect rendering.
Of course this works only for the gl_x11 engine... and for
now only when using EGL... and only on some drivers...
damn limitations.
Direct rendering should work on more platforms (eg. some desktop
nvidia cards with the EGL drivers).
Add version param to context_create.
Add support for 1.1 contexts in the GL_X11 engine, and checks
for version in all other engines (return NULL).
Add API wrappers for all OpenGL-ES 1.1 APIs (normal and debug
modes).
Welp, glGetString() crashes if called before eglInit... And this
piece of code is now useless because "safe native" mode is not
used anymore (safe_native is never read).
Remove all safe native-related code.
This will be used to increase the chances of having direct
rendering (no fallback to FBO) even if the window is rotated.
The client is then responsible for handling the view rotation.
@feature
This was affecting use of GL backend when having a transparent window. It
is actually a fix for a bug reported by Thanatermesis. It has been inspired
by D1229.
To reproduce the issue just do ELM_ACCEL=gl elementary_test -to "Icon transparent".
