bare bones opengl weston client sample

[jegde jedge]

Thank you so much, that did the trick!

Next Question :)
On the same code, on the same hardware...
I am getting the glut 60 fps limit when running my app using the glut
front end via
gnome and X.
I am getting ~24 fps using the simple-egl front end on top of wayland.
I also noticed the display using wayland likes to hover around 20 fps.

Is there some kind of throttle built into the frame rate for the
redraw callback?

Thank you.
