Clutter Backends - EGL and X11

[mahesh gawali <maheshgawali outlook com>]

If I choose backend as (on ARM v7 target)

export CLUTTER_BACKEND='eglnative'

export CLUTTER_INPUT_BACKEND='null'

my simple clutter application(display a rectangle) does not display anything. it does not error out either.

FPS is shown as around 60 in the terminal, but i do not get anything displayed.

It works fine when I choose 

export CLUTTER_BACKEND='x11'

export CLUTTER_INPUT_BACKEND='null'

Also I checked on how x11 and eglnative backends are setup in clutter-cogl. Looks like

in file clutter-backend-eglnative.c

EGLDisplay clutter_egl_get_egl_display (void)

is never called during setting up eglnative backend.
