When collaborating, cursor position is shared: while user1 is pressing and user2 move the cursor over the canvas without touching, the pencil draw a line jumping from user1 position to user2 position.

Steps to reproduce the behavior:

  1. Open a collaborative lavagna in two different computers.
  2. Start drawing and keep pressing on computer A
  3. Just move the mouse in computer B
  4. A line is drawn from position in computer A to position in computer B

Expected behavior

Nothing should be drawn when mouse is just moving without pressing in computer B, if A is drawing.
