| CanvasBase * | iCanvas | 
A tool for transforming the selected objects on the canvas.
Supports moving, rotating, scaling, and stretching.

Constructor starts transformation.
After constructing a TransformTool, you must call isValid() to ensure that the transformation can be performed.
A transformation can fail because the selection contains pinned objects, or because the initial mouse position is identical to the transformation origin.
| bool TransformTool::isValid | ( | ) | const | 
Check that the transformation can be performed.
| 
 | virtual | 
Called when a mouse button is pressed or released on the canvas.
button is 1, 2, or 3, with Shift/Ctrl/Alt/Meta modifiers added in (as defined in CanvasBase::TModifiers. press is true for button-down, and false for button-up.
Reimplemented from ipe::Tool.
| 
 | virtual | 
Called when the mouse is moved on the canvas.
Reimplemented from ipe::Tool.
| 
 | virtual | 
Report the final transformation chosen.
The implementation in TransformTool does nothing. Derived classes should reimplement report().
