-Expected changes to come:
-
-* Collision avoidance
-    * Slot Collider
-    * Kern Collider
-    * Associated glyph for exclusion
-    * bounding octabox and subboxes
-* FSM compression
-* Setting segment feature values in action code, for pass constraint testing
-* Move gralloc/realloc from once per rule to once per pass to speed up font loading.
-
-Questions:
-* Do we support glyphid as a slot attribute?
