UI

Thoughts

• For nested scrollable containers - should the inner container handle the scroll and stop parents from scrolling, otherwise let parent scroll?
• Should layouts be involved in scrollable areas? Reporting a list of the visible components? Maybe a layout is sent the bounds, the visible bounds, and it needs to update each component as clipped or not?
• Should there be a setting so the current bounds of a component is used during clipping to avoid calling the render function? Maybe pass the corners through the components transform to get the transformed points to do a transformed test? Other post-processing can interfere with points or generate data that could be outside the grid. That's where visualBounds is useful. Maybe allow some padding around the normal bounds as well?
• Virtual grid?
• Make LayoutCenter?
