Triangle: Resizing of the tool is broken

Now coping creates a full copy of already created item. Copy has it's own content (like video, audio or folder) and stores original item properties (like locked, pos, size, freezed e.t.c.).

It's icon is temporary.

Behavior implemented:
1. Can interact with all items without showing items frames (but ToolBar shows).
2. Cannot move items, but can drag images.
3. Selected items appears deselected when Play tool chosen.
4. Play tool don't requires selecting of item before interacts.
5. Cursor looks like tool icon in text and image widgets (should be the same in any others widgets, but now in w3c is not).

When it rotates with the tool bracket gestures to change its size are not consistent. The parameters of size change does not take into account the position of the bracket.

Changing the size of the bracket using the angles opposite the right angle does not work all the time, we must rotate the bracket so you can change its size
