The RPC and sync library mechanisms were removed for now; they never really worked and contained several obvious bugs. Need to consider if syncs are useful at all during the compose time, or just used during intro.
Delays and samples are not implemented yet and thus the tests are skipped, as these require parsing the delay and sample tables also. Various macronames were changed to be more sensible and consistent i.e. ATTAC was changed to ATTACK. GatesLow and GatesHigh was removed for the time being and the tracker will just have to know they are the SHAPE and COLOR parameters. SU_SPEED was changed to take a parameter so the parser picks it up.
The bridge.go now just assumes that the library you want is built in the build/ directory. It's probably a lot better idea than using wherever the latest build was; this way the same build is always used for the library.
The main interface is render_samples function, which renders several samples in one call,
to limit the number of calls from Go to C. This is compiled into a library, which is then
linked and called from bridge.go.
