Summary:
It is need in case Evas_3D_Mesh created with not normileze texture coordinate
and flag repeat mode for Evas_3D_Texture
Additional info see here https://phab.enlightenment.org/conpherence/54/
Use Evas_GL_Image for generation texture unit for Evas_3D_Texture

Invert the meaning of scaled (w,h), so that im->(w,h) corresponds
to the final scaled size, and the original size is stored directly
in the texture itself.
This simplifies code a little bit.
Also, lift the limitation on the maximum texture size, as those
virtual textures are not limited by GPU texture size.
Use the same method as for map masking:
- Pass absolute geometry of the mask to the push functions,
- Compute absolute position in the shader (like gl_Position)
and apply scaling factor + offset to sample the mask.
Masking now uses a single vec4 attribute instead of hi-jacking
other vertices.
This way, all masking shaders share the same code and are way
simpler. On the other hand, the vertex shaders have a little bit
more work to do.
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).
Edje may not set the filled flag on an image even if its fill
properties make it fill the whole object. For masking, it can
then be considered as a filled image.
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...)
This is a new attempt at avoiding reload of an image
that failed to load during async preload.
See 42d2f8a12b (reverted).
I still can't figure out why setting load_error does not
work as expected (E pager becomes blank).
these were static rect cutouts, so they stayed around on exit and thus
we "lost" them. this nukes them on context free and each new frame.
fixes the "leak"
In case of png, grayscale with transparency format (transparency doesn't mean the png has alpha channel)
gl doesn't prepare that format render.
In this case, set it argb8888 to convert the data in the png loader.
@fix
We prefer ETC2 textures when ETC2 support has been detected.
According to the spec, glCompressedTexSubImage2D should work
for ETC2.
Try even with ETC1. This may fail at runtime. The fallback path
is very dubious right now but without a proper test case I'm
not sure which approach to take.
We can also imagine cases where the GPU supports TexSubImage for
ETC1 but ETC2 is not supported at all. This will need testing, as
this case is not handled.
@feature
In evas_gl_common_image_draw, if an image is drawn with a fresh context,
containing no clip and no cutouts, then it will be wrongly clipped to
the source image size instead of the destination surface size.
This case seems to never happen, ever, since the contexts are always
fully set by the render functions.
@fix
Quick and dirty solution to support the OpenGL engine:
[1] Allocate CPU buffers
[2] Render text and process all effects to these buffers
[3] Push final image as an OpenGL texture.
This patch implements [1].
Simply call the appropriate cache2 functions when possible
and check for usage of cache2 whenever an evas_cache_ function
is called.
This effectively adds cserve2 image (data) load support for the
GL engines. Fonts were already working out-of-the-box.
NOTE: when using Evas_Object image preload infrastructure the GL texture
upload was uploaded from the main loop during the rendering stage. This
could lead to some frame drop during fast animation due to the time needed
to upload that texture.
This patch fix this problem by uploading a small texture quickly (16x16)
and waiting for going back to the main loop to be able to use the same GL
context from another thread to do the texture upload asynchronously without
blocking the main loop.
