  1. Insert a new frame
  2. Change the zoom level (for example to 50%)
  3. Drag the title bar to move the frame

The frame moves slower than the mouse.

The same applies for moving stickies.

  • Calculating the movement vector should be in the elements' parent space.
  • We should transfom the vector (0,0) -> (newX, newY) from the coodinates MouseCapture works with to the parent space.
  • However since our the scene coordinates and the MouseCapture coordinates differ only by translation and we're interested in a vector, it is enough to transform by sceneToParent matrix.
  • Tranforming a vector is done by transforming its 2 points and substracting the result.
