// Experiment: use native scroll for ribbons and view...

|
// Factors:
|

// + the browser will do all the heavy lifting and do it faster

// than we can ever hope to do it in JS (assumption)
|
|
// - will require us to add an extra container per ribbon
|

//
|
|
// Experiment result:
|

// - more uniform and fast across browsers
|
|
// (except FF -- can't disable scrollbars, need to cheat)
|
|
// - less controllable (inertia, gestures, ...)
|
