Corrects calculation of intermediate buffer width multiplier.
...
Specifically: I had failed to factor in that the multiplied-up input frequency might be less than than the full width of the bitmap.
The Atari and MSX in particular now look much better.

"Doubles" the bandwidth given to composite signals.

Because I suspect it may inadvertently have been halved previously. I'm investigating.

Initialize all const members.

Without this change, GCC versions >4.8 will error with things like:
```

Switched to using quads for intermediate draws. The specific concern is the flexibility offered in the GL spec as to line drawing algorithms. And even if a driver implements exactly to spec then it should omit the final pixel.

Reduced precision of input phase, but I'm not necessarily persuaded by it as a move. However it's clear that something is off in that whole area. But if phase is locked by output position, do I need to retain this level of complexity? Also ensured that intermediate buffers prior to the final are sampled using the nearest sampling mode, also to reduce precision errors.

Switched back to full buffer clearing. Until I can figure out the source of noise.

Started taking steps towards using a texture barrier where possible to reduce all of my framebuffer binds. Some output appears, but it's not correct.

Definitively eliminated the additional y filtering step; if I'm going to work to ensure always four samples per colour cycle, I can put the channel separation coefficients directly into their shaders, cutting down on samples.

Temporarily disabled composite processing to show the pure stream. Fixed both automatic calculations of phase — per line and, at input, per pixel.

Temporarily disabled my attempt to be clever with bilinear filtering when applying a lowpass filter. Will need to investigate.

Experimental: up the chroma accuracy, just let the luma go straight through. Subject to figuring out how I'm still losing so much precision.

Restored proper colour separation, but somewhere a massive hit in horizontal resolution is happening — much greater than one would expect from the sample size picked. So investigation to come.
2017-01-03 22:32:07 -05:00

Added the option for both intermediate and output shaders to use only a portion of the input/output texture; made an attempt to pick an appropriate proportion in order to align signal sampling with the colour subcarrier.

Moved underscores, removed indirections where they're not necessary, converted those names that were still looking very Objective-C and moved the GL fence variable into the private area, where it should always have been.

Even better: why include the 'Input' prefix when there's only one?

Renamed the 'input buffer builder' to the 'input texture builder' to be explicit about what sort of buffer, and killed the prefix since it's namespaced. Also switched to std::vector.

Both pathways start with a buffer that clears to black. So no need to keep going on about it.
