We're currently considering intervals open at one extremity, in order to
ensure that a given value is always contained in a single interval.
This creates problems with synthetic clamp intervals [1, +inf), for
t == +inf (no interval can contain it).
Treat intervals as closed at both extremities instead. This introduces
some ambiguitiy for overlapping values (contained in both adjacent
intervals), but solves the more serious problem above.

For vertical gradients, we rely on LinearIntervalProcessor to yield a
fAdvX == +inf, thanks to division by dx (== +/-0).
But certain degenerate values may cause the numerator to also collapse
to 0, resulting in fAdvX == NaN.
Instead or relying on float semantics, pin fAdvX to +inf explicitly for
vertical gradients.

We have a couple ways to detect CPU features on ARM:
- on ARMv8, getauxval(AT_HWCAP)
- on ARMv7, getauxval(AT_HWCAP) and cpu-features.h
This guards each of these methods with preprocessor guards to match
exactly when we can use them. Today they're sort of a mix of that and
higher level expectations about particular build and operating systems.
I'm looking into doing this directly by reading CPU registers,
much like we do for x86 further up the file.
None of this is super important right now, so as long as we don't decide
that we have these features when we don't, things will be fine. It's no
big deal for now if we fail to detect them.

WindowContext still supports color spaces, but not other color
types. Any off-screen rendering is the app's responsibility.
This change also adds (working) F16 support to viewer. Note that
the previous 10-bit and FP16 support in WindowContext was broken.
There was no code to push the off-screen canvas to the window.
If you ever made it to the unreachable off-screen code path in
createSurface, it would have simply stopped drawing.
The decision to limit the window's gamut to sRGB is mostly driven
by my desire to add real-time editing of gamut. This design lets
us do that, without tearing down and rebuilding the window for
every change. An application could still supply a different gamut
via setDisplayParams and render directly to the back buffer with
proper color correction.
