Replace notcurses_render_to_file() and
notcurses_render_to_buffer() with variants that work
on arbitrary piles (the former only worked on the standard
pile). Rewrite the former as trivial wrappers around the
latter, and deprecate the former. Closes#1770.
All our diagnostic macros required a struct notcurses from
which to extract the loglevel. Eliminate this parameter,
and update all caller sites. Add a library-wide (but not
exported) loglevel variable, and set it from both
notcurses_core_init() and ncdirect_core_init(). Add two
new direct mode flags, NCDIRECT_OPTION_VERBOSE and
NCDIRECT_OPTION_VERY_VERBOSE, mapping them to
NCLOGLEVEL_WARNING and NCLOGLEVEL_INFO respectively.
Closes#1690.
- add type aliases: NcDirectF (NcVisual alias), NcDirectV (NcPlane alias).
- implement wrapper methods for the `ncdirect_*` functions on NcDirectF.
- the methods over NcDirectF are prefixed with `ncdirectf_` to distinguish them
from the other NcVisual methods (since they are both type aliases, they
share their methods).
- fix typos in `direct.h`:
- ncdirect_geom_frame > ncdirectf_geom()
- ncdirect_render_loaded_frame > ncdirectf_render()
- add NcVGeom struct.
- minor fixes & rustfmt.
ncplane_as_rgba: genericize across blitters
ncplane_as_rgba() previously was implemented explicitly
in terms of NCBLIT_2x1. it now uses the `egcs` field of the
`blitset`. this supports NCBLIT_2x2 and NCBLIT_3x2 in
ncplane_rgba(). Closes#1490.
