[M40 Merge] Fixed that webview is crushed on resizing viewport.

webView is crushed when creating/removing IME and rotating device.
It is caused by diffrence between the size of egl surface rendered
and glViewport arguments. The arguments were set by evas geometry size,
but it was different from the size of rendered surface.
