I wonder if you could make this work with Rex's boundary plugin.
You might have to lock the mouse onto a object, and use boundary on the object.
Take a look at the plugin and see if you can figure it out, if not I can try to throw something together as an example.

You can resize(WIP), rotate, change opacity, change the Z-Index order and import/export the project composition. Also you can import external images that will be saved in Base64.
Is focused to work with sprites, no draws or pixels. Still is all a bit mess, will see <img src="{SMILIES_PATH}/icon_razz.gif" alt=":P" title="Razz">
