NOTE: The draw_buffers extension might need to be checked more and
wrapped, if it can have adverse effects on how Evas works (could
it replace the default render target?).
This adds support for the following extensions:
- disjoint_timer_query
- occlusion_query_boolean
- alpha_test
- draw_buffers
- read_buffer
- read_buffer_front
- framebuffer_blit
This will mark some extension functions as "safe", which means
we don't need to wrap them in order to expose them.
All the known extensions from Evas_GL_API have been marked as safe
for now.
In the future, we may encounter extensions that are not safe
out of the box, but can be wrapped. At that time, we will have
to mark them as safe but return the pointer to the wrapper instead.
Until then, only whitelisted extensions will be supported.
@feature
The idea is that normal opengl applications might very well want to
check for an extension using the usual string and not have to do
something special just because they're using evas_gl and not egl.
Some shader files (shd) were not included in EXTRA_DIST. This didn't break
the build because the .x file was correctly generated.
I guess the missing files in previous releases also had no impact because
the .h files would be generated and shipped.
Also generate the enum automagically. New shaders need to be added
to Makefile_Evas.am.
All shaders will be in a single .x (C) file.
There shall be no more useless .h files.
This also removes the need for awk (replaced by sed and bash stuff)
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: Wayland windows should follow X11 windows fairly closely,
thus only set withdrawn property if they are override windows. If not,
internal dialogs do not show up in Enlightenment (wayland-only).

Summary: This commit fixes compiler warning:
modules/evas/engines/gl_common/evas_gl_3d.c:1322:48: warning: 'ld' may
be used uninitialized in this function [-Wmaybe-uninitialized]. We
declare 'ld' as NULL now, and check it is valid before using it.

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

Summary: The function prototype for eng_context_create has recently
changed in gl_common, however nobody thought it wise to update all
engines using it, so this commit fixes the function for the gl_drm
engine.

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.
Summary: Apparently, somewhere down the line, the function prototype
for eng_context_create was changed in the EVGL_Interface, but nobody
decided to fix All engines. This commit fixes the function prototype
for evgl_eng_context_create

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.
When using EGL, this function should return the properties of
a surface. Limited to a subset of known attributes.
Right now, this function will only work fine with EGL.
GLX support or any other engine is not implemented.
