d4ac79b0af Attempts to introduce a full-on processing pipeline, in theory putting me two shaders away from completion.
Well, subject to finding the last flashing bug and updating the multimachine, anyway.

75bc0e451d Reintroduces the accumulation texture.

16dfeb3fc8 Discards empty lines, yet makes some attempt at restoring transparency.
The two things conflict more than a little, so work to do.
