// 	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, ...)
 | 
						|
// 		- is affected by scaling in a bad way -- paralax...
 | 
						|
//
 | 
						|
// 	Conclusion:
 | 
						|
// 		- this again brings us to using code to control the scroll
 | 
						|
// 		  which in turn defeats the original purpose of avoiding
 | 
						|
// 		  extra complexity...
