Get rid of annoying empty line in notcurses-view (and ncvisuals at offsets in general)
Implement most of the Selector widget. Need to add styling and scrolling still. #166
Reenable ubuntu focal build
Subtitles! We decode them, and display them in notcurses-view. If ncvisual_simple_streamer() is provided an extra ncplane, it will use it to display subtitles. #95
We now build Python by default, as things are working much better.
ncplane_set_base() now takes channel, attrword, and EGC, so you can usually avoid having to set up and release a cell. ncplane_set_base_cell() takes over duty from ncplane_set_base() for ease of conversion.
notcurses-demo and notcurses-view now both accept a 0 for delay multiplier, meaning 'go as fast as you possibly can'. Very small multipliers (e.g. 0.00001) no longer cause floating point exceptions.
fading routines no longer cause floating point exceptions on very small timescales.
If we're going to issue smcup to switch to the alternate screen,
flush immediately after doing so. Otherwise, subsequent output
prior to the first render can be swept away. See growlight issue
75: https://github.com/dankamongmen/growlight/issues/75. In the
demo, we now get this output either (a) at the beginning (if smcup
is inhibited) or (b) at the end (default). Only perform our pause
on startup in case (a).
Introduce the new type 'ncdirect', a stripped-down 'notcurses'
suitable for inline modification of regular output. Used the new
type because otherwise there were going to be if(directmode) checks
everywhere. Direct mode encompasses only colorizing and styling.
Add new man page notcurses_directmode(3). Add new section to README.
Add new PoC using direct mode RGB. Update demo table summary to use
direct mode.
As it turns out, we can't portably load the initial terminal contents
(there are some hacks of various EXTREME nature, but none of them are
worth it for the rather limited benefit). The O(1)-time damage
inference requires knowledge of what was previously present to
inibit unnecessary draws. We would then need some special cell value
indicating "not yet written to" to distinguish a purposeful null
cell from an initial cell. Again, we could do this, but for what value?
Finally, the idea of clearing new area on SIGWINCH was always flawed,
as we can't do that from a signal handler.
With the advent of direct mode #77, the reason for this largely goes
away in any case.
* palette_set: update pal256 damage map #230
* drone: use newest builders
* palette: send oc on exit for color reset #285
* palette_new: copy existing palette in #230
* Python: use checkRGB everywhere
* more palette unit testing
* add ncplane_set_*_palindex()
* render fg palindex #230
* palette index color is out of 1000
* jungle demo works #253
Profiling with `perf` revealed the fprintf() inside term_esc_rgb()
to dominate our performance. Replace it with a u8->str lookup table
and a hand-assembled string fed into a single fputs(). On a 80x70
xfce4-terminal geometry, this wins 20%+ FPS on the demo, w00t!
Huzzah for profiling!

* still more man page work
* notcurses_lines, last of the man pages i think
* panelreel man page #244
* debian: ruby-ronn->pandoc
* debian: full multiarch compliance
* debian: symbols file
* pandoc: fix syntax for lexgrog
* fm6.mkv: strip audio
* pandoc: fix up apropos man syntax #249
* ncurses_lines man page
* higher planes stomp wide glyphs
* broken unit test
* develop out widestomp PoC
* fix notcurses_at_yx()
* fix up dig_visible_cell() return value
* refuse wide glyph on last column #242
* set adjacent cell wide when rendering #158
* xray: eliminate weird color flicker
* witherworm: don't eat wide glyphs
* unit test for boxed glyph
* uniblock: no need to emit so many U+200Es
* witherworm: remove wide glyph hack
When we emit a glyph that has no background pixels (i.e.
the U+2588 FULL BLOCK glyph), there's no need to emit a
background color change.
Eagle demo currently has hand-coded elision. Results from
80x70 runs using the `-c` parameter:
No optimization: 12.63MiB
Hand-optimized: 12.48MiB
New scheme, no hand-coded optimization: 12.45MiB
w00t!

enable mouse events in the demo. spawn a thread from main() which
brokers all input events. it will consume mouse events, and
publish keyboard events to a queue. rewrite all demo notcurses_getc()
calls to demo_getc() equivalents.
Allow -1 in move specification to remain where we are on that
axis (#210), necessary for context-sensitive aligned output.
Add _aligned forms to printf and vprintf. Invert various output
functions so that simpler form is static inline wrapper around
more complicated form, rather than complicated form being a
static inline composition, facilitating atomic move+output. All
output forms now have a simple form (no alignment, placement at
cursor), an _aligned() form, and a _yx() form.
Request and parse up mouse messages. We handle up to 11 mouse
buttons, 3 modifiers (currently thrown away), motion while
holding down a button, and loss/gain of focus. I've added twelve
new NCKEYs: one for each button, and one for release. In addition,
I've introduced the 'ncinput' struct, which encodes the nckey plus
extra data. The only extra data thus far is coordinates for mouse
events. It is not necessary to provide a ncinput to all input
functions; NULL can be provided if the caller doesn't care about
details. All demos are updated. notcurses-input has been updated
to decode full information of returned ncinputs.
