Note: You will need you to recompile 0ad in order to try out the changes in this branch.

My attempt at ticket #3038. I have implemented a new UI element scrollable. It inherits from both CImage and CScrollbarOwner. It can be used as a simple replacement for any <object/> or <object type="image"/> UI element : <object type="scrollable"/>.

This may not be the optimal solution, and other suggestions are welcome.

Known problems:

• Clipping, that is to say elements being hidden when not 'inside' the visual boundaries of the parent object, is not implemented. I'm actually a little unsure how to implement this as I have a feeling it might require major modification to how the UI system currently works within 0AD.
