Kitty conflates an RGB background specification that aligns
with the default background color with that actual background
color. This can result in translucent background when we're
expecting opaque ones. Detect kitty (strstr check of terminal
name for "kitty"), and if it's active, mark `bg_collides_default`
with the rgb of the default background color. For now, we assume
this to be (0,0,0), but we ought improve it by determining (or
setting, if that's impossible) the precise default bg color.
Closes#1117.
When the -t switch is provided to notcurses-view, its
floating-point argument is the number of seconds for
which we delay after showing an image. When this is used,
the standard "press any key to continue" prompt is not
displayed, and indeed keybindings are not honored. This
can be used for a slideshow, or just for fullscreen display
involving no user interaction. It does not apply in the
case of -L for looping. Closes#1229.
Thread out ncls to perform the media decode in different threads, in parallel. Only the display needs be locked. On a directory of 200 files on my 39070X, this speeds ncls from ~5s to ~1s. On 75 files, we go from ~.5s to ~.2s. On a single file, we lose about 5%. To facilitate this, ncdirect_render_image() has been split into two helpers, ncdirect_render_frame() and ncdirect_raster_frame().
Progress bars now support four 32-bit channels in ncprogbar_options, and uses them to color a gradient. The redraw procedure has been changed from O(n) to O(1). ASCII progress bars have been repaired. Closes#1213.
Tremendous thanks to @kaniini, @Ikke and everyone else over
at Alpine Linux for helping to chase this down. I blundered
in ncplane_reparent() when reparenting a root plane with
children (the children need to come into the root plane
list). This will hopefully fix our amd64 failures on Alpine
since late 2.0.x. Closes#1197.
