Works better than the kitty-print DCS escape code as that tends to get
interleaved with other writes to the tty since the loop infrastructure
writes in a separate I/O thread.
Uses a private API that allows us to control the amount of blurring.
While using a private API is obviously not ideal, it is used by both
iTerm.app and Apple's own Terminal.app, so hopefully it should stick
around. Fixes#6135
This has the side-effect of also applying the same luminance based gamma
adjustment for multipass rendering as we do for single pass rendering.
This *may* make things look worse with very low background_opacity
values, since in such cases the actual background color can be quite
different from the background color we are adjusting against.
Use scale + size as the fixed strategy. This is because static looks
bad with translucent windows (the cell area ends up a different opacity
than the newly exposed window area).
Also disable live resize begin/end events on Wayland since they are not
reliable.
On platforms that support live resize begin/end use a separately
configurable pause time before the screen is redrawn.
Fixes#6341
This adds a config option called text_fg_override_threshold that
specifies a percentage difference luminance below which the
foreground color will be overridden. The foreground color is set
to white if the background is dark or black if the background is
light. The default is 0, and the computations will only be
performed if the option is set.
Many programs output colors that look good with the author's
terminal's color scheme but which are completely illegible with
other color schemes. This allows the user ensure that there is
always sufficient contrast to read the text on the screen.
I originally implemented this is as a parameter on
text_composition_strategy. For that to work, the option needed to
take _up to_ rather than _exactly_ the number of available
parameters. While it now has nothing to do with the new feature,
it seems like that change should be made anyway, so I'm leaving
it in for now.

Since we want existing configs to continue working, this also
makes it so that rather than taking exactly two parameters,
text_composition_strategy takes one--three parameters, using the
default values for those not specified.
