a8acadbe13 Gives the shader builders freer rein over what to use as inputs, and turns angles into a varying.
All dropping out during the never-ending diagnosis at play here.

46d756d298 Starts towards a flattening of the intermediate video processing.
Immediate issue: using x position to index into a bitmap sampled at the input data rate doesn't allow for the disconnection between input rate and output speed provided by the flywheels.

fd579a019b Introduces a new scan source data type, motivated by the reasoning used by the Oric.
Specifically: it'll allow PCM sampling of the potentially arbitrary composite generation logic of various machines.

d4ac79b0af Attempts to introduce a full-on processing pipeline, in theory putting me two shaders away from completion.
