* Paint sprixels in order, bottom-to-top
We don't want to have to track sprixel order whenever someone
moves an ncplane, so just keep a list growing backwards as we
pass top-to-bottom in notcurses_render_internal(). Each time
we hit a sprixel plane, splice it out of the sprixel list, and
add it to the front of our temporary list. When we hit the
bottom, stick this temporary list on the end of our existing
list (any such planes are to be deleted, which comes before
drawing). Closes#1575.
* reorder collected sprixellist; solves kitty but breaks sixel =/ #1575
* remove debugging cruft
* [rust] fix up mergedown mutability

- 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.
- separate the methods into its own module.
- add constants NCVISUAL_OPTION_ADDALPHA, NCVISUAL_OPTION_HORALIGNED, NCVISUAL_OPTION_VERALIGNED
- add NcRgba type.
- update the docs.
deprecate ncvisual_geom() in favor of new ncvisual_blitter_geom(), which allows caller to get the blitter used. replace the checks and calculations in ncvisual_render() with a call to ncvisual_blitter_geom(), unifying the two paths (and eliminating several bugs in the unloved ncvisual_geom()).
- improve NcVisual.from_rgba documentation.
- fix Notcurses.term_dim_yx documentation.
- new example `poc-planebase` to help find the bug.
- improve full-capabilities example a little.
- rename and refactor NcPlane method rgba() to as_rgba().
- add example `issue-rgba` that shows a problem when the plane has text.
- refactor `error_ref` & `error_ref_mut` macros to allow custom return values
