started better boundary detection using hysteresis
improved boundary extension by hysteresis, fixed a mistake
improved the boundary segmentation, added parameters, some cleanup
ported some android changes
added boundary pruning
added the option of selecting whether or not to use hysteresis and pruning in boundary segmentation
started to add edge chain handling
continued work with edge chains, not finished
continued implementing edge chain generation, still not finished
fixed a terrible bug in list_insert_sorted
working version of finding boundaries
started work on typed pointers and context
more work on edge chain joining, still quite little progress
more edge chain parser work
still more progress with the parsing algorithm
some small sketching
just some minor changes
adding some utility functions for boundary parsing
new boundary parsing compiles but does not work yet
fixed a few errors and added debug prints, runs but does not work correctly
