Subpools are for grouping components by some criterion. Any component that has a rangeid callback will be grouped with other components that return the same render id. Note that the ordering of components within a group will be affected by adding a component into a group that comes before that group (or removing a component). Component pools can have multiple groups, added and removed dynamically, but removing a group should (currently) be done only when empty.
