NOTE: I would like to do the same with software SDL 16bits engine.
But as we don't have a buffer_16 backend, I am likely to just remove
it and use buffer conversion code to match a 16bits target. This
will come with a performance impact, that will make it useless. So
I am just tempted to completly remove it.

This optimization is significant for rendering to a large surface
because it'l save an extra copy overhead as well as an extra rendering pass.
To enable it, you can give EVAS_GL_OPTIONS_DIRECT hint in the surface
config options_bits. The following conditions have to be met in order
for evas to render directly into the Evas' window. If they are not met, the
engine will fallback to rendering to an FBO as it normally does.
conditions:
1.) All the GL calls have to be called using the pixel_get_callback function.
This is necessary for the evas object order to be maintained.
2.) Alpha must be disabled on the image ojbect that renders evas_gl.
3.) No rotation allowed.
One way to override above condition is to set EVAS_GL_DIRECT_OVERRIDE=1 but
there is no guarantee in its behavior.
Currently, this optimization is added for gl_x11 engine only.

quickly when uf your-encoded anything due to using IFAST decoder (and
encoder). this does drop speed for decode and encode (except encoding
< 60% quality where it now uses IFAST), but we don't see progressively
worse artifacts.
