Missing feature? It would be nice to add parameters to modify speed/accel of a whole pattern.

Bulletml's spec is quite light on details. Speed has no unit, etc. So there are two choices:

do the computation in terms of abstract units and let the calling code do the math (mostly a matrix multiplication)
put those constants in env and to the math in real units (screen pixels)

To simplify the library code I'd go for the first one. It is also possible to provide a module that does the math.
