ncurses on FreeBSD still uses termcap(5) while foot works fine with
xterm-256color sans status line and visible bell. Having more than
one ncurses version installed may break other applications.
Document -Dterminfo=false uses --term=xterm-256color by default
Base compiler on BSDs doesn't look where packages are installed to
avoid tainting build environment. When system fcft is installed to
the same prefix as wayland-client it passes CFLAGS that satisfy both
but when using subprojects/fcft there's a build error.

epoll/timerfd are Linux-only but BSDs have a shim via kqueue.
libwayland on FreeBSD uses epoll-shim by default, so the build may
fail at linking instead of compilation stage.

* ‘term’ struct contains an array of 160 fcft glyph pointers
* the glyph pointers are lazily allocated when we need to draw a box
drawings character
* Filtering out box drawings characters is easy - they are (except
unicode 13, which isn’t handled yet )all in a single range.
Dependency chains:
* pgolib -> terminal.c -> terminal.h -> wayland.h
* vtlib -> csi.c -> config.h -> wayland.h
wayland.h includes <primary-selection-unstable-v1.h>, which must be
generated by a custom_target() rule *before* any sources that require
it are built. Failure to fully specify these dependencies can otherwise
result in a race condition, where a dependent source file gets compiled
(and fails with a "header not found" error) before the header itself
has been generated.
* Split up source files into several static libraries: misc + vtlib
* Add a new executable, pgo, that links to vtlib
* pgo is kind of like a mock test:
- provides stub implementations of functions not present in vtlib
- sets up a dummy terminal instance
- calls vt_from_slave() with static (pre-generated) content
Instead of writing (and logging errors for) every parameter, one at a
time, send all fixed size data in a single struct, followed by all the
variable length data.
* New function: rgb_to_hsl()
* New function: hsl_to_rgb()
* Replace XTerm’s hls_to_rgb() with our own, hsl_to_rgb().
* Ensure hue/lum/sat values are within range before calling
hsl_to_rgb()
Note that sixels’ use the following primary hues:
* blue: 0°
* red: 120
* green: 240°
While “standard” HSL uses:
* red: 0°
* green: 120°
* blue: 240°
Thus, we need to adjust the sixel’s hue value before calling
hsl_to_rgb().
Use the new fcft_set_scaling_filter() API to use a non-default scaling
filter.
By default, we use lanczo3, the ‘best’ filter. This overrides the
default in fcft, which is ‘cubic’ filtering.
