Specify boundary in pixels

It would be great if there was an option to specify boundary in pixels

boundary: {top: 0, bottom: 0, left: 0, right: 300px}

@desandro i think this has some interest from different people, maybe im wrong #70 in my situation some simple code:

  if (this.position.x > someVar || this.position.x < otherVar){
     this.disable();
  }

so in this case dragging on the x-axis has a stop when users drags item too far left or too far right. but gets tricky when i need to figure how to re-enable dragging once the user is back within range.

with something like an offsetLimit proposed in #70 or like proposed above there’s a boundary setup by variables rather than a dom element such as the parent container

hopefully this makes sense, let me know.

Closing this issue as it didn’t get enough public interest. Alas! 👻
