Triangle: Resizing of the tool is broken

1st we remove original widget, then we disable undo stack, create a copy of widget and make it a tool. Then undo stack enables back. That widget has tool as parent, so we not need to manage him by scene.

The eraser erases more than it should delete

Corrected imported text position.
Strokes for lines and polygons has the same color as fill color.

Fixed svg:a section. Now cff fully compatible with online validator http://validator.imsglobal.org/iwb/index.jsp?validate=package

Show Desktop: "Erase all" button isn't work

UBCffAdaptor adapted to current validator to have less errors (http://validator.imsglobal.org/iwb/index.jsp?validate=package)
