Add touch area to image widget
Currently, a transparent button needs to be overlaid over the image in order to achieve touch effect. Please consider implementing touch area functionality for the image widget.
Implemented in v0.11.4 (already available).
Added touch response to image and video widgets. Touching the image (video) widget now sends the message in the following format: @<uid>, where <uid> denotes the widget's unique identifier set by the UID: parameter.
