[marktaipan-cvisionai]

Category Bugfix

Problem Incorrect statement in comments that the show() function of canvas-applet-element is called after updateFrame() is called.

Request

• Fix comment
• Create new variable that is set to true when this._frame does not match data.frame in show()
• Set this._offscreenRoi = [0, 0, 1, 1] by default if the applet frame is different
