I find the scale of UIPinchGestureRecognizer is confusing, so I did two experiments below, two ways to do the same thing.

Method 1

gestureRecognizer.scale start with 1.0 at the beginning of pinch (gestureRecognizer.state == .began), and gestureRecognizer.scale in later state (.changed or .end) is always based on that, for example, if the view size is view_size at the beginning of pinch (might not be the same with the original size orig_view_size), gestureRecognizer.scale always starts with 1.0, and if it becomes 2.0 later, it's size will be 2 * view_size, so the scale always based on that when the pinch starts. And we can get the scale at the beginning of pinch (gestureRecognizer.state == .began) lastScale = self.imageView.frame.width/self.imageView.bounds.size.width, so the scale of the original image now should be lastScale * gestureRecognizer.scale

• lastScale: The scale of last round of Pinch, a round of Pinch is from state.start to state.end, and the scale is based on the o

bigbluebutton video UI enhancement

There are two feature requests relate to bigbluebutton video UI.

1 Add outline for selfview

This is used for guiding the user to adjust the header and shoulder place before camera, by showing an outline in selfview video.

To do this we can simply add a foreground image, and put that image in the center of selfview window.
