Description Simon Fraser (smfr) 2015-05-18 19:05:10 PDT 
We currently store a list of offsets for X and Y axes for snap points. When a scroller has descendants with 'scroll-snap-coordinate' values, we need to store x,y points, not independent lists of x and y offsets.

Spec is actually unclear on this point, and it's under discussion.
Comment 2 yisibl 2015-07-08 19:58:10 PDT 
We must support offset value(Firefox 39 also supported: https://developer.mozilla.org/en-US/docs/Web/CSS/scroll-snap-coordinate)

Like this:

scroll-snap-coordinate: top right 10px;
scroll-snap-coordinate: bottom 10px right 20px;

and scroll-snap-destination

scroll-snap-destination: top right 10px;
scroll-snap-destination: bottom 10px right 20px;

Name:	scroll-snap-coordinate
Value:	none | <position>#

Also scroll-snap-coordinate: none is not support.
