bee0d09877 Splits display update and draw functions. 
On the Mac, draw is now called without an update for resizing events, and
anything else requested by AppKit. In all other cases — including from
the SDL version — both are called as if they were still a single function.

db078c7363 Minor tweak: don't start counting phase from zero. 
This should ensure no first pixel issues resulting from clamping.

6b4f6971de Disables upper limit on frame buffer size. 
Filtering is sufficiently imperfect as to make this justifiable only when performance requires it. So I need a test for that. Marked as TODO.

694783efe9 Brings S-Video inside the group that filters luminance. 
Thereby revealing some sort of error in offset selection.

16731661e8 Switches back to being explicit about the colour burst phase. 
Some sort of phase inversion otherwise seems to be achievable by software that switch modes often.

7bb90c78d9 Resolves out-of-bounds initial condition whenever this loop began with start_line = 2047. 
This, I believe, was the remaining cause of screen flashes.

a6e61ef83b Reverts the clear colour to black. 
The change was related to debugging; it was not intentionally committed.

d4134cd0d8 Restores proper colour phase to the Apple II. 
Given that its timing errors were fixed, this also switches back to using 'default' colour bursts — i.e. ones with implicit phase. The Apple II continues to be an excellent bellwether for issues in the pipeline, and this helps further to ensure that.

2f9e825728 Forces the outward-communicated composite angles to have the same precision as the cycle counts. 
While also making a minor improvement to output range. Which is neither here nor there.

2f491b5be1 Reintroduces fragment snapping for composite colour sampling. 
Thereby uncovers some sort of slightly-off recording of scan lines. On the Apple II, individual scans reach the ScanTarget at a density of exactly 0.25 colour cycles per pixel. So that timing information propagates exactly. But the whole lines that are composed via ::announce end up trying to fit 0.250154 colour cycles per pixel. Which creates a phase error as the display progresses from left to right.

This will need to be resolved in order to be able to fix the Apple II's intended colour phase. But, also, it's probably what was wrong with the Oric. And, quite possibly, why the single-step shader didn't work.
