'ViewportInitialized' flag in gl_context has to be reset to '0'
when the current context is unbound via a eglMakeCurrent call with
all of 'NULL' resources (surfaces and context).
This is to make sure the viewport of the context is re-initialized
when the same context is bound to new read and draw surfaces
(or same surfaces but with different size.) next time when the
context is made current again.
