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

CELL_ALPHA_OPAQUE et al were defined as 0..3, meaning
CELL_ALPHA_SHIFT had to be used to compare them to their
channel representations. Instead, define them in said
representation outright, eliminating the need to shift while
retaining arithmetic properties, and zero initialization for
CELL_ALPHA_OPAQUE. Eliminate CELL_ALPHA_SHIFT #738.
Add convenience function ncplane_home(). Add an ncblitter_e param
to ncplane_qrcode(), and split int maxversion into value-result
int* ymax and int* xmax. Write the actual sizes of the resulting
visual into these parameters. Update the qrcode demo. Add the
qrcode PoC. Update demos to ncplane_home(), where possible.
ncplane_qrcode() now takes an ncblitter_e and two value-result int*s
in the place of a single value int. The final size of the displayed qrcode
is written to *ymax and *xmax. If the code can't fit within the specified
dimensions, an error is returned. Standard rules for pluggable blitters
apply regarding fallback etc. #699
The Plot unit tests were reaching directly into the objects,
which meant the implementations couldn't include anything
we didn't want public. This was annoying, so I've changed it.
This required adding ncdplot_sample() and ncuplot_sample(),
which we should have had anyway.
Very simple take at ncplane_puttext(), a new function for linebroken text. Also some very basic unit tests. I doubt this works very well yet, but it handles the simplest cases #682. Added nclog(), internal function for logging. #520

This represents an essentially complete rewrite of ncvisual and associated code. It had two major goals:
Improve the ncvisual API based off lessons learned, pursuant to the upcoming API freeze. In particular, I wanted to:
decouple ncvisuals from ncplanes. It should be possible to render a ncvisual to multiple planes, with different scaling each time. It should be possible to create an ncvisual without a plane, etc.
normalize the various ways of constructing an ncvisual -- file, memory, plane, etc.
Support multiple blitters, from 7-bit ASCII to Sixel. This required writing the blitters in several cases, and they're not yet in their final implementations (but the API is fine)
I have not yet unified Plots and Visuals, and might not, given that the Plot code works fine. We could at this point implement Plots in terms of Visuals, though -- the blitter backend range has been unified. Sixel is not yet implemented, though it is listed.
There is a new POC tool, blitter. It renders its arguments using all possible blitter+scaling combinations. Another new POC, resize, displays its argument, then resizes it to the screen size and displays that, explicitly making use of ncvisual_resize() rather than a scaling parameter to ncvisual_render().
This also eliminates some memory leaks and bugs we were seeing in trunk, and brings in Sixel scaffolding.
The C++ wrapper will also need patching back up; I cut most of it down while wrestling with this crap, urk.
Closes#638, #562, and #622.
Replace the singly-linked z-axis with a doubly-linked list,
and reimplement all z-axis moves as O(1) functions.
Eliminate ncplane_move_{above/below}_unsafe(), as there are no
longer unsafe moves.
Unify ffmpeg/oiio/null implementations, where possible. This effectively
required placing all three in the same file, which meant they're all now
C++. Update FFmpeg implemenation to be C++-usable. Implement
ncvisual_rotate_cw() and ncvisual_rotate_ccw() #515. Move most of tetris
over to Visual from Plane #558. Add bgra_to_rgba(), necessary for
creating ncvisual from BGRA memory. Implement ncvisual_from_rgba()
and ncvisual_from_bgra() #557. Add unit tests on ncvisual rotation.
* ncplane_at_* and ncplane_at_cursor_*
We had notcurses_at_yx() expanding into three distinct parts of
the cell structure, and ncplane_at_yx() / ncplane_at_cursor()
writing directly to a cell. It was annoying to remember which
was which. The latter two now have a signature matching
notcurses_at_yx(), while the old functionality has been moved
to ncplane_at_yx_cell() and ncplane_at_cursor_yx(). #476
* packaging: s/libtinfo/Terminfo/g
* rust: add stddim_yx()
* rust: check for valid init in unit tests
* rust: serialize up tests
* constify notcurses_term_dim_yx()
* rust: add dim wrappers
* remove notcurses_resize() from public API #367
* call notcurses_resize() from notcurses_refresh() #367
Resolves#410. notcurses_at_yx() accepted a cell*, but the
gcluster of this cell was always set to 0. The EGC is instead
a heap-allocated copy, returned as the primary return value.
This is due to the absence of an egcpool to bind against.
Existing callers can be converted thus:
* instead of passing cell 'c', pass &(c)->attrword, &(c)->channels
* either initialize 'c' with CELL_TRIVIAL_INITIALIZER, or set its
gcluster field to 0 following the call
I've updated all calls from tests/demos, updated the docs, and
updated the C++ and Python wrappers.
Add ncplane_bound(3). This allows a new plane N to be created in the
*bound* state relative to another ncplane B. If B moves, N moves the
same amount. If N is moved, the coordinates are taken relative to B
as opposed to the standard plane. If B is destroyed, N is destroyed.
Each plane can have many planes bound to it, but can only be bound to
a single plane. Add ncplane_reparent(3). This allows a plane to be
detached from any plane to which it is bound, and optionally rebound
to a new plane. The standard plane cannot be reparented.
Documentation and unit tests have been added for both.
ncplane_mergedown() is similar to the "Merge down" operation
in the GIMP. It writes to the destination plane the result
of rendering the source and destination frames per se.
Add four new fields to notcurses_options: margin_{tblr}, which requests margins to the top, right, bottom, and left. Render only within those margins, leaving the screen otherwise untouched (well, cleared if using the alternate screen). #293

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.
