Daniel Eklöf	f3c5b82c82	config: add tweak.bold-text-in-bright-amount ... By how much to increase the luminance when brightening bold fonts. This was previously hard-coded to a factor of 1.3, which is now the default value of the new config option. Closes #1434	2023-07-28 15:40:07 +02:00
Daniel Eklöf	e0297daa1f	hsl: add our own implementations of rgb-to-hsl and hsl-to-rgb ... * 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().	2020-11-15 19:45:33 +01:00
