[Magnifier - 3] Reduce number of calls to PixelCopy
* Magnifier#show() takes snapshots of the content and displays
them in the Magnifier bitmap
* calling show(...) consecutive times with the same arguments is
a no-op if already showing (to cater with the miriad of motion
events produced by touch which end up calling show(...))
* introduced Magnifier#invalidate(...) which, if currently
showing, forces updating the content using the last configuration
* clamped the start horizontal value of the Rect which delimits the
content to show in order to avoid distorting the rendering of the
magnifier content
* fixed invalidating the magnifier (invalidate() does not
automatically call invalidate(RectF) !)
