• Added the flag NCVISUAL_OPTION_NOINTERPOLATE to use non-interpolative scaling in ncvisual_render(). ncvisual_render() without a multimedia engine will now use this method for any requested scaling (previously, scaling was not performed without a linked multimedia backend).
• NCVISUAL_OPTION_BLEND used with NCBLIT_PIXEL will now, when the Kitty graphics protocol is in use, cut the alpha of each pixel in half.
• ncvisual_inflate() has been rewritten as a wrapper around the new function ncvisual_resize_noninterpolative(), and deprecated. It will be removed for ABI3. Godspeed, ncvisual_inflate(); we hardly knew ye.
• ncdirectf_render() has been changed to accept a ncvisual_options, replacing and extending its four final arguments. Sorry about the breakage here, but ncdirectf_render() was introduced pretty recently (2.3.1). As a result, ncdirectf_render() and ncdirect_stream() now honor NCVISUAL_OPTION_BLEND and NCVISUAL_OPTION_NOINTERPOLATE. All of this also applies to ncdirect_geomf().
• ncplayer now accepts -n to force non-interpolative scaling.
• A new binary is installed, notcurses-info. It prints information about the terminal environment in which it runs. More information is available from its man page, notcurses-info(1).
• Added ncdirect_light_box(), ncdirect_heavy_box(), nccells_light_box(), and nccells_heavy_box(). Publicized nccells_ascii_box(). All are static inline.
• A bug was fixed in ncplane_move_yx(): root planes were being moved relatively instead of absolutely. This was never the intended behavior.
• It was previously possible to pass NULL as the second parameter of ncplane_mergedown_simple(), and have the standard plane be used as the destination. This is no longer supported, since the source plane could be in another pile. An error will instead be returned.
• Fixed a bug in ncdirect_box() where default/palette-indexed colors weren't properly used on the top and bottom borders.
• Added notcurses_detected_terminal() and ncdirect_detected_terminal().
