This is really dumb, we weren't processing backlogged packets from the opcsink buffer. This is the cause of the ugly delays I'd been seeing in the 'waves' demo.

This is a big improvement in dithering quality: Near zero, where we have the most problem with visible flicker, this uses a linear curve instead of the usual nonlinear curve.

This can get out of hand if the client is producing frames faster than our USB device accepts them, leading to large kernel-space queues and high latency. This patch causes intermediate frames to be dropped, but it will always update the device with the latest frame buffer state.

This is way too verbose

Configuration is now no longer mandatory.

This is hella verbose, quit it.

After discussing with Ping, changed the format of the color correction command to use a MIDI-style SysEx command in OPC.

The server now works end-to-end, yay.
