TETRAEDGE: Add ScummVM option to hide empty inventory box
The way to open inventory in the Tetraedge version of Syberia doesn't seem elegant to me. There is always a rather strange box in the bottom right corner of the screen that can partially hide some bits of the background or hotspot markers, for example: at the waiting room in the notary office and a stand for a collection item on the train. ScummVM places the box slightly lower than e.g. native Android version (I can't test it for MacOS) and at the very border of the screen - which may be a little better, but still not that good when compared to the Virtools version - with right-click inventory access and the box only visible when an inventory item is selected. IMHO the classic Windows version looks and feels better when playing with a mouse.
Since the inventory box is hidden during dialogue and in-game cutscenes, it seems that there should be a way to hide it using some sort of a new hack.
