[Interest] Qt5/OMAP4/EGLFS: Strange animation behaviour

Just wanted to point out that the EGL spec seems to specify that VSYNC 
should be enabled by default:

http://www.khronos.org/registry/egl/sdk/docs/man/xhtml/eglSwapInterval.html

"If interval is set to a value of 0, buffer swaps are not synchronized 
to a video frame, and the swap happens as soon as the render is 
complete. interval is silently clamped to minimum and maximum 
implementation dependent valuesbefore being stored; these values are 
defined by EGLConfig attributes EGL_MIN_SWAP_INTERVAL and 
EGL_MAX_SWAP_INTERVAL respectively."

and

"The default swap interval is 1."
