Guard against attempts to output glyphs to a sprixelated
plane in ncplane_putc_yx(), the lowest-level common end
of all ncplane_put*() functions. Add unit test #1572.
Go ahead and allow the standard plane to be used with
NCBLIT_PIXEL, but enforce placement at the origin with
any provided plane. Implement this in ncvisual_blitter_geom()
so that it applies everywhere #1572.

- add new Notcurses methods: `canhalfblock()` and `canquadrant()`.
- add doc links to NCBLIT_* flags from the capabilities methods.
- update the full-capabilites example to include `canhalfblock`, `canquadrant`,
`canchangecolor` and `canfade` functions.
- rustfmt
- move blitter type, NCBLIT_* constants and NcPixelGeometry from the plane module to the visual module.
- add information about blitter graceful degradation the NcBlitter type.
- add cross linking from/to the NCVISUAL_OPTION_NODEGRADE flag.
- update the full-capabilites example to include braille.
Whether a draw is due to a move or a simple invalidation,
we need to go ahead and apply any outstanding deepclean to
the sixel beforehand. This eliminates the last bit of
flicker in the intro demo, at the orca's first location.
Also, never emit a '-$' sequence when deepcleaning a sixel.
Closes#1574. Closes#1568.
