0499dbd4cf Align Scan to be a multiple of four bytes 
Some GPUs (e.g. r600) require the stride of vertex attributes to be a
multiple of four bytes, add two bytes of padding to the Scan struct to
meet this alignment requirement and reduce driver CPU overhead.

637ec35d6a Adds getters for standard colour-space conversion matrices. 
These are just more details on the meaning of the colour spaces, so I think they belong here.

8374a5e579 Adds superficially correct compositeSampleLuminance8Phase8 function. 
Thereby uncovering a minor error in my decoding of colour phase.

525233e10b Ensures all input data types are parseable in Metal. 
Though now I need to think a bit more about the best way to compose signal-type conversions, and whether output-type calculations (i.e. gamma, brightness) are applied.

c1dc42a094 Add comment on latent design aim. 
In the hope that I don't forget why I did this.

bdcf266e45 Having learnt a bit more: eliminates Metal attribute tags, switches to more natural expression of structs. 
Also thereby eliminates the need for a forced alignas(4) on various structs.

4c9418f59a Guarantees alignof(4) on all GPU-bound structures. 
Taken as given: Metal's requirement here is reasonable enough that it'll either be the same as other frameworks, or at least possibly help them down a fast path.

a71c5946f0 Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine. 
Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.

d97a073d1b Adds the necessary routine for all machines to be able to respond to get_scan_status. 
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.

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. 
Well, subject to finding the last flashing bug and updating the multimachine, anyway.
