The previous commit modifies the concept of direct rendering
vs. indirect rendering, so some runtime checks (in debug mode
only) will fail.
This commit introduces two new engine functions:
- gl_get_pixels_pre
- gl_get_pixels_post
The latter will be used in a later patch for optimization.
not changed.
Automatically fallback to indirect rendering on FBO or X11 Pixmap
if the Evas Object Image is not marked as dirty. This should
improve the performance and/or power consumption in those
rare cases where this area of the canvas needs to be redrawn
but the GL content has not changed.
@feature
Summary:
gl_get_pixels_set is called in evas_object_image_render
even when evas gl is not used.
As gl_get_pixels_set does not actually call evas gl functions,
we can safely remove evgl_init macro here.

Summary:
Currently dynamic hint set is implemented using eglMapImageSEC extension,
which is no longer supported by any drivers (should be deprecated)
This patch implements dynamic hint set using Khronos extension EGL_TIZEN_image_native_surface.
Since tbm surface library is required for this, libtbm.so is queried at context new.

jpeg: I also fixed a few minor style issues and two warnings (bad function
names, glsym instead of secsym).
The function image_scaled_update() frees() the old scaled image
passed as input if it doesn't match the old dimensions. This commit
will avoid double frees.
This will currently optimize most of the masks when using the
GL engine[1].
This is a very special case that adds a highly optimized path
for masking in GL. It works by creating a virtual image, containing
a pointer to the original image and a new geometry[2].
Instead of creating a new FBO-based surface (image_map_surface),
we refer to the original image and adjust the mask geometry on
the fly.
KNOWN BUGS:
- masking a map with such a scaled image is now broken.
[1] Right now all masks are simple Evas Object Image, so that means
all cases of masking, except masks of masks, or masks of maps,
will be optimized with this new method.
[2] This virtual image mechanism is still quite hackish and may
be improved (for memory usage, refcounting, etc...)
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.
