I'm sorry that I shared the broken ascii images.
Although when I sent the acsii image, I'd checked it on my text editor.
It has been messed. I don't know why my ascii image was broken.

therefore I attached a text file of the ascii image which describes
Tizen Window System Architecture and a relation between display server
and wayland-egl client.

Comparing to gbm, tbm backend also calls drm apis directly. this is
example for tbm-vc4 backend.[1]

For supporting the gbm on tizen, tizen has tbm backend for the gbm. [2]
