Long-planned changes for API/ABI3 #1777
* remove old-style notcurses_ rendering functions
* Make notcurses_render() a static inline wrapper around
ncpile_render(). Remove the deprecated
notcurses_render_to_file() and ncpile_render_to_file().
* ncstrwidth() becomes static inline wrapper #1777
* remove deprecated ncvisual_subtitle()
* kill ncvisual_inflate(), long deprecated #1777
* remove deprecated palette256 wrappers #1777
* kill ncplane_new() #1777
* remove deprecated renderfp field from notcurses_options #1777
* reorder ncstats fields to match documentation #1777
* kill deprecated style functions #1777
* ncplane_move{top, bottom} become static inline #1777
** ncplane_pixelgeom -> ncplane_pixel_geom() #1777
* ncstyle functions ought return uint16_t #1777#2200
* ncvisualplane_create: provide new pile functionality #1462
* [heuristics] GNU screen 4x never has rgb
* [BitmapSmoothMove] only WARN in test until sixel supports this #2258
* contour: enable sextants
* interp PoC: clean up ncvisual #2266
* ncselector_options: constify string arguments
* Constify strings in selector/mselector_items
Use internal types to track items within the
selector/mselector widgets, rather than pressing the
user-provided item structs into double-duty. With this
change, we can constify the strings within those
user-provided items. Do so, also removing the internal-side
elements. Update documentation. Closes#2267.
* constify ncmenu_item/_section strings
* constify strings in nctabbed_options
* notcurses-demo FPS graph: back to straight seconds
* remove unused wchar_from_utf8()
* nstrwidth_valid(): properly initialize bytes/width
* [ncneofetch] use GetSystemInfo on Windows
Deprecate notcurses_mouse_{enable, disable}. Reimplement
them for now as wrappers around notcurses_mice_enable().
New function notcurses_mice_disable() is a static inline
wrapper around notcurses_mice_enable(). The latter
function takes an unsigned bitmask of event types. We
now turn on the "all motion" tracking DECSET if
NCMICE_MOVE_EVENT is requested. Update the documentation,
and kill some obsolete lines. Add the ypx and xpx fields
to ncinput, to indicate pixel offset within a cell. Add
nckey NCKEY_MOTION for button-free motion events. Update
notcurses-input to pass NCMICE_ALL_EVENTS and decode
NCKEY_MOTION. Only emit mouse sequences when connected
to a TTY (or GPM). Closes#2320.
Request RGB XTGETTCAP.
Fix bug in error check in notcurses_render_to_buffer().
Decode multiple XTGETTCAP responses.
