Fix alignment of this.
Change state manager interface to match my interface. Next up is inlining those function pointers.
Copy over my rewinder to rewind.c. Apparently the makefile didn't pick it up, and telling it to do that would be a waste of time, since the plan is merging them anyways.
Kill empty files.
Trim off this; from now on, the rewinder is responsible for rounding and allocation.
Fix this part, so we avoid a pointless memcpy. Rename this function.
Inline these functions. Should mostly work now...
