Those 2 new values are here to avoid using environment variables
that have side effects on the whole application.
I'm actually wondering if we shouldn't just kill off the env
vars altogether. Also, direct override is a terrible option that
should never be used.
Memory optimization can make sense (needs more testing tho).
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:
Added additional texture and framebuffer for rendering meshes to it.
Added function that return OpenGL id additional texture
Added function that return color from target texture by mouse pick coordinates
Added function that render need meshes to target texture
Added engine wrappers for possibility force render to texture

The memory usage graph was going up and to the right!
I was told this is always a good thing!
... maybe not this time :)
Hopefully I didn't forget a case. An intense session of
genlist scrolling with masks all over the place and masks
of masks didn't show any glitch, crash or memory leak.
There was a problem when checking whether the current surface
is compatible with direct rendering. In case of client-side
rotation (it's a flag set on the surface by the app), a surface
can be directly rendered even if the rotation is not 0.
But, before this patch, it was assumed that the surface was
current. Which doesn't make sense because make_current is
called by the pixel callback, from the application, and this
happens *after* we check for direct rendering.
As a consequence, it was not possible to mix directly rendered
surfaces with FBO-based ones, and use client-side rotation.
This patch should solve that issue.
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
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).
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.
@feature
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 is the first step to introduce a common gl infrastructure for all gl based backend.
For now it is strictly doing the exact same thing that the gl_x11 was doing, but I already
spoted that a lot of the optimization in gl_x11 where not incorporated in other gl backend.
So this is going to help everyone by sharing more code on a crucial part of our infrastructure.
