Part 1 of a two-part revolution in Linux console graphics. Map all the line-drawing Unicode characters to similar glyphs. This means all our nice corners freely translate into rigid corners etc in the console, rather than hateful default characters (usually black diamonds). The demo and all widgets now look correct when drawing lines and boxes. Next, we'll add the actual glyphs for the block-drawing characters, and we'll have the finest graphics ever seen on a text-mode Linux console. #201
* use ioctl(KDGETMODE) to detect Linux console
* diagnostic on KDGETMODE
* add logdebug()
* unit test for notcurses_drop_planes(), add ncplane_putnstr_aligned()
* linuxconsole PoC
* linuxconsole: dump unicode->font table
* linuxconsole: explode glyphs
* linuxconsole: show 7 glyphs per 'line'
* linuxconjammer: shim console font with half blocks
* signals: handler for SIGTERM
* man pages: update notcurses_init() for options
* add NCOPTION_NO_FONT_CHANGES #201
Tons of work on ncreel (#627, #749, #694)
Improve reel demo: get input wired up once more, avoid the FPS demo at bottom, print pointer and line count in each tablet, use new ncreel API. Improve notcurses-ncreel explorer: kill memory leaks (#694), draw tablets better, use new ncreel API. Fix bug in ncreel core where cruft could be left on the screen, via a very gross brute force algorithm. I'll likely come back and make this a bit less ghastly in the future #749. Remove weird one-off input system from ncreel, residue from outcurses. Make some of the normalizing changes speced out in #627
* ncreel: give each tablet an index, and print it #749
* reel: eliminate FIXME + param to insert_tabler() #749
* ncreel: label tablets with their adress to correlate against debugging logs #749
* more terminal environment variable notes
* TERMS.md: add Sakura, st
* ncreel: move legend out of reel proper
* ncreel_options: dump min/max_supported_rows/cols #627
* ncreel: remove weird one-off input layer #627
* ncreel: add ncreel_offer_input()
* reel demo: call demo_getc()
* reel demo: rig up input to demo main
* ncreel: drop ncreel_del_focused(), properly bind tablets
* reel demo: don't free up necessary plane
* ncreel: don't pull absolute locations of tablets
* ncreel: place tablets correctly in boundrel
* reel demo: add back support for left/right
* reel demo: restore thread movement
* ncreel: remove a great deal of complexity
* reel demo: stay out of FPS graph's way
* ncreel: give each tablet an index, and print it #749

* reel: brute force decruftification, how embarrassing #749
If we don't have setaf/setab, then we're not going to set color.
OK, fine. Don't regard it as an error during
notcurses_rasterization(), just don't emit the escape. This is
necessary to run on terminals like vt100, which in turn is
necessary to run unit tests properly on Redhat's koji.
Also, use notcurses_canfade() to avoid just breaking during
fades in intro and trans demos.
When we don't have an actual terminal in ncdirect, return
placeholder 80x24 for ncdirect_dim_y()/ncdirect_dim_x(), but
don't go querying e.g. a redirected file for its dimensions.
Similarly, only request info about cursor position from a true
TTY (we're otherwise likely to hang, or at best get meaningless
data). Rewrite 'direct' PoC to use ncdirect_dim_*().
Add tty_emit(). Closes#752.
* Some things go to the FILE* we're provided. Some can only go to a controlling terminal. Check to see if the FILE we're given is a TTY. If not, open up /dev/tty #752.
* term_emit(): fflush() can return EAGAIN. Loop on it to eliminate a rare error on shutdown that particularly affected unit tests (where we start and shut down Notcurses many times in a row).
* sgr poc: check return value of setlocale()
* drone: run all unit tests
* CMake: add some tests using PoCs
* ncneofetch: print even small palettes
