 Views use gl.scissor to cut the viewport into segments. You tie a view to a tracking div which then controls the position and bounds of the viewport. This allows you to have multiple views with a single, performant canvas. These views will follow their tracking elements, scroll along, resize, etc.
 
-It is advisable to re-connect the event system to a parent that contains both the canvas and the html content. This ensures that both are accessible/selectable and even allows you to mount controls or other deeper integrations into your view.
