 Update border, and constrain elements
 
+## Transforming a transformed Container's child DisplayObjects
+
+It is useful to support transforming elements within a container that might also have some transformations applied.
+
+Use case: design area has been resized/zoomed.
+
+Currently the coordinate systems are out, and the boundary mechanism fails too.
+
+Come up with a design / plan...
+
+We might need to introduce functions for transforming through parent layers.
+
+## Decomposing tools into classes
+
+Conceptually tool sequence is:
+
+- Provides a handle that can be dragged
+- Take the handle's start and current events, the registration point
+- Produces a potential transformation (of various types)
+- Transformation gets limited by new bounds
+- DisplayObject gets updated with final transform
+
+Tools therefore need to know:
+
+- Orientation point
+- How to limit a transformation? Surely this is deterministic, but in some cases the math is hard, such as scaling
+
+Tools don't need to know
+
+## Types of bounds
+
+Oriented Bounds - bounds that have been positioned, rotated, scaled with the target
+Simple Boundary Bounds - bounds that wrap the transformed oriented bounds
+Complex Boundary Bounds - bounds that wrap the complexities of a shape: eg vector graphics, various primitive shapes, or images with some pixel analysis.
+
+We'll settle for a simple bounds approach, since reorienting isn't common.
+
+Current issue: we rely on un-oriented bounds to collide with boundary, resulting in the objects crossing over the boundary. Perhaps this is ok.
