It adds TIZEN_image_native_surface extension string to _EGLExtensions.
And it adds a routine of creating an EGLImage from a tbm_surface.
- section overview
from
https://www.khronos.org/registry/EGL/extensions/TIZEN/EGL_TIZEN_image_native_surface.txt
"Tizen Buffer Manager (TBM) is a user space, generic memory management
framework to create and share memory buffers between different system
components. This extension enables using a Tizen Buffer Manager (TBM)
surface object (struct tbm_surface_h) as an EGLImage source."
