ncneofetch was previously direct mode followed by rendered mode with
margins, a Frankenstein application if one ever existed. Rewrite it
using CLI mode, extending the latter as necessary to accomplish this
task. We now have one fewer dependency on direct mode, we have better
proven out CLI mode, and we get a ~30% reduction in ncneofetch runtime.
Good stuff! Closes#2030.
Add ncplane_scrollup() and ncplane_scrollup_child()
Cleans up ncport.h
Eliminates some inconsequential memory leaks in ncneofetch
Add SPRIXEL_UNSEEN to avoid invalid moves on
not-yet-displayed sprixels
ncplane_as_rgba: genericize across blitters
ncplane_as_rgba() previously was implemented explicitly
in terms of NCBLIT_2x1. it now uses the `egcs` field of the
`blitset`. this supports NCBLIT_2x2 and NCBLIT_3x2 in
ncplane_rgba(). Closes#1490.
* Paint sprixels in order, bottom-to-top
We don't want to have to track sprixel order whenever someone
moves an ncplane, so just keep a list growing backwards as we
pass top-to-bottom in notcurses_render_internal(). Each time
we hit a sprixel plane, splice it out of the sprixel list, and
add it to the front of our temporary list. When we hit the
bottom, stick this temporary list on the end of our existing
list (any such planes are to be deleted, which comes before
drawing). Closes#1575.
* reorder collected sprixellist; solves kitty but breaks sixel =/ #1575
* remove debugging cruft
* [rust] fix up mergedown mutability
