Add transition when swiping from fullscreen to enter PiP

There are some artifacts actually come from test app implementation
- when in landscape fullscreen, sourceRectHint would include the black
  background on both sides
- when settled in PiP, app does the transition which causes the final
  glitch
Would address these later in the test app itself
