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!
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.
The primary resource for this work was Dickey at al's "XTerm Control
Sequences", https://invisible-island.net/xterm/ctlseqs/ctlseqs.html.

Implement a fairly conservative, line-granularity, two-level damage map. One on the overall notcurses object is dirtied by planar moves, creations, deletions, and resizes. One on each ncplane is dirtied by glyph output, media rendering, fades, and erasure. #83 This has some definite false positives: a hidden plane which moves will damage a bunch of lines unnecessarily. For now, don't do things like that :D.
Extra byte per line per plane, shouldn't be a problem.
Two new stats for cell elisions and emissions
Allow keypress to interrupt view-demo
ncvisual_stream() now allows a callback per frame
Allow ncvisual_open() to create its own, perfectly-sized, ncplane #128

on netcurses-demo, we're eliding about half of the total cells via this damage map. that's pretty fucking sweet! FPS increase of about 50% -- I'll take that any day of the fuckin' week, boyo. w00t!
