String and art adder functions now perform type checks, in case of
memory errors that somehow result in classes changing type. Which in
itself is a strange thing to happen.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
Restructure the add string or art functions so they don't take a pointer
to a pointer, which may have caused issues when receiving a nil string
from the caller. Instead, take a plain pointer, and return the object,
returning the ID of the object to a pointer to an int64_t.
Also change several prototypes and functions to use _Nonnull or
_Nullable where appropriate.

This condition would underflow when skipping a bunch of samples on the
start of playback, or otherwise seeking, and could cause an unsigned
underflow, which would cause the subsequent vDSP_vflt32 to overread into
the MAD sample buffer and crash.

As the decimator has shown to be twice as loud as it should be, the
volume should be reduced by half when converting DSD to PCM with it.

Pure downsampling is slower, but may or may not be more accurate. Though
probably not worth it. It did help me realize a minor error, though.

This prevents crashes where inputs were not returning either properties
or metadata blocks and the file open cache was attempting to cache the
resulting nil pointer as if it were valid. Also prevent the metadata
redundant string coalescing from processing nil objects as well, in case
it's used that way somewhere else.

I'm not sure about macOS Ventura, but stable releases of macOS, at

Gate registering observers behind a check variable in the object state,
which will be zero initialized by the Objective-C runtime, and will
prevent the class from erroneously unregistering observers without them
being registered in the first place. Apparently, services cannot be
unregistered if they were never registered first, or else an exception
will be thrown upon attempting to unregister them. This fixes a crash on
startup in the now several times running failure to work properly on
legacy Macs without Metal graphics, now that the new visualization
system has been implemented.
It's probably not worth bringing back the previous Core Graphics based
visualizer method anyway, as on those same legacy machines, it was
causing out of control CPU usage by WindowServer. At least on modern
Macs, any amount of 60fps UI updating will cause WindowServer to use
about 45% of a core, regardless of how many apps are drawing that much
at once.

If the system has no working Metal devices, disable the visualization.
The legacy visualization was also too slow for said systems to handle
reasonably anyway, so I guess it's safe to say that they shouldn't have
to handle any visualizers at all. At least have working audio playback,
of course, since that is the primary function of the application. Too
bad that the OpenGL renderers don't work on my scene, it would be nice
to have a fallback there. GL 4.1 crashes on an M1, and both GL 4.1 and
3.2 crash with SIGFPE division by zero error on Intel Macs without Metal
devices. Meh.
