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.
Writing a partial escape can easily lock up a terminal. This
is especially relevant when working with bitmaps, as they're
thousands or even millions of times longer than a typical
escape. Immediately before writing, block SIGINT, SIGQUIT, and
SIGTERM in the writing thread, and unblock them upon emerging
(at which point we'll immediately see any queued signal
get delivered). Don't block signals like SIGSEGV that would
seem indicative of actual problems. For this to actually work,
all other threads must also have the signals masked; we thus
now add them to the signal mask of notcurses_getc(), rather
than deleting them. Closes#1416.
