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).

We're not using NCBLIT_2x2 by default because it warps the
aspect ratio. If we're using NCSCALE_STRETCH, though, we've
(1) already indicated that aspect ratio isn't terribly
important to us and (2) are trying to maximize the space.
Since NCBLIT_2x2 is best for large images anyway, make it
the default when NCSCALE_STRECTH is being used.
Remove all explicit uses of NCBLIT_2x2 when NCSCALE_STRETCH
is being used in notcurses-demo.
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

When we first begin operations, we need emit a cursor homing, which
we were not doing for the first line. As a result, the first row
didn't show up until you rendered something else, and even then
didn't show up unless you changed it (as it was otherwise undamaged).
This explains a lot of mystery behavior in notcurses-demo that I've
long told myself I'd hallucinated or imagined. Hurrah! but also
supershittytothemax! Thanks Marek Habersack for pointing out something
which led to an experiment which led to chasing this down once and
forever. Closes#619, w00t!
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.
This is to make it possible, in the future, to create multiple instances
of `NotCurses` for multiple terminals. The first instance of
`NotCurses` becomes the default one, so that any instances of other
classes that aren't explicitly created with a pointer to another
`NotCurses` instance still work as expected.
Note that currently trying to call `notcurses_init` twice results in the
following error for me:
0x55555559bfc0 is already registered for signals
Couldn't drop signals: 0x55555559bfc0 != 0x5555555b6720
terminate called after throwing an instance of 'ncpp::init_error*'
Program received signal SIGABRT, Aborted.
The error is signalled by `setup_signals` and the pointer shown in the
message points to the first `struct notcurses` instance created.
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.

Rather than inspecting CMAKE_BUILD_TYPE manually and setting
DEBUG_OPTIONS based off the results, set CMAKE_{C/CXX}_FLAGS_DEBUG,
and allow that to be picked up by CMake #565. Remove repeated -W
flags that were all over the place, making them global compiler
flags. Remove repeated FORTIFY=2 definition that was all over the
place, making it a global compiler definition. Remove all uses of
${DEBUG_FLAGS}. Also, since CMake doesn't define a CMAKE_BUILD_TYPE
by default, instead just setting neither debugging nor optimization
flags, in what seems a pretty fucking boneheaded move, set it by
default to RelWithDebInfo. ugh. Explicitly disuse unused PoC variables.

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
Nick prefers error handling based on exceptions in all cases, while I
prefer to save exception handling for truly exceptional situations -
function parameter validation and class constructor. However, there's no
need to not support both approaches, to be chosen at the discretion of
the developer.
NCPP follows RAII and all classes throw exceptions from their
constructors in case they cannot initialize properly. Likewise,
functions taking pointers that are required validate them and throw
exceptions whenever the requirement isn't met.
This commit goes one step further in that it enables optional validation
of notcurses function return values and throwing an
exception (`ncpp::call_error`) should the function signal an error. This
is disabled by default but it can be enabled by defining the
`NCPP_EXCEPTIONS_PLEASE` macro (preferably on the command line or
before *each* inclusion of any NCPP headers).
Out of necessity, this breaks the ABI (plus I found a handful of minor
issues in the code), but I think it's worth having this support in
place.

ncvisual_render() now returns the number of cells emitted
rather than just 0/-1. -1 is still returned on failure.
Rather than 0 for length meaning "all possible length", it
now means 0, and -1 means "all possible length". All demos,
tests, and PoCs have been updated. #422
I noticed while running benchmarks against ranges of widths that
we failed on certain widths. I traced this down to a repeatable
failure when run with the -c flag at the 104x52 resolution. At this
geometry and PRNG seed, we NULLed out the first subwindow of fallin',
but didn't recompress the window array. On the next loop we thus used
it again, and segfaulted out. This fixes that up. We now pass 100% of
the benchmarks, whereas we were failing about 3% before #407.

* NotCurses: drop_planes (`ncplane_drop_planes`)
* NcReel: constructor which takes `Plane&`
* Visual: constructors which take `Plane const*`, `Plane&` and `Plane const&`)

the C++ builds and does absolutely nothing interesting.
Broke:
* All exceptions throw temporary objects instead of allocated
instances. Less typing in `catch` :P (and more conventional)
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.
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.
