There is an issue while changing view's size and changing fixed layout size in event view:EVAS_CALLBACK_RESIZE.  The result was that scrollbar's max position was not calculated properly.

Basically ewk_view_fixed_layout_size_set() was triggering smart_calculate() in the backing store while FrameView did not have visible content size updated yet, so the scrollbar's max positions were computed incorrectly.  If we call ewk_view_fixed_layout_size_set() from the new callback, then the issue does not exist, because FrameView's visible content size is updated right before the callback function is called.

Thanks,
Miroslaw
