// Why isn't the off()-function working below. When i click anywhere in the document it checks if the
// target has a class called "drawing". If so, it activates the mousemove-event which fetches the
// mouses current position. The idea is to remove that event when i relase the mouse but it doesn't
// seem to work?

		$(document).on({
			mousedown: function(e) {
				// If we are clicking on a drawing
				if($(e.target).hasClass('drawing')) {
					// Mouse move
					$(document).on('mousemove', function(e) {
						getMousePos(e);
					});
				}
			},
			mouseup: function(e) {
				// Mouse move
				$(document).off('mousemove');
			}
		});
