title: Vue-js-modal resizable issue
body: <p>By default, vue-js-modal scales from the central point, which is pretty strange. Is it possible to scale it like all other windows (according to one of the edges)?</p>
  
  <p>EDIT
  On the official page (<a href="http://vue-js-modal.yev.io/" rel="nofollow noreferrer">http://vue-js-modal.yev.io/</a>), when you 'click' resizable, you can see what I mean. In the docs there is a line, which describes 'resizable' attribute: "If true allows resizing the modal window, keeping it in the center of the screen". I didn't find other info and don't want to change the source code. I don't want it to be keeping in the center, because I think that this is not correct. </p>
