Animations run faster with "pixlet serve" than on Tidbyt

[chrisbateman]

Animations run significantly faster with pixlet serve than they do on an actual Tidbyt device:

• As best as I can tell with a stopwatch, an animation that takes 3.5s in the browser will take 4.5s on an actual Tidbyt.
• It seems like a Root delay of 33-34 will make animations run about as fast on a Tidbyt as they do by default with pixlet serve.
• Exception: unchanging frames do animate at the expected speed

This makes it tricky to get timings right and to align animation length with app cycle speeds. It might be ideal to find a way to simulate slower animations when running pixlet serve.
