Remove references to dlib and OpenCV. Added TODOs to use with OSF.
Replaced some dlib types with generic structs.
Code compiles now but does not work because all coordinates are zero.
Update to Cubism SDK 4-r.2. Incompatible scaling changes.
NOTE: Scale factors and translate co-ordinates worked out using
the previous release will need to be updated, because the SDK has
changed how scaling is handled.
Add support for models that use Cubism 2.1 style parameter IDs
Backported from mouse-tracker-for-cubism
