Wez Furlong 8cb74c62d2 allow setting selection colors with alpha values ... This commit allows the following configuration: ``` wezterm -n --config 'colors = { selection_fg = "clear", selection_bg = "rgba:50% 50% 50% 50%" }' ``` which sets the selection_bg to fully transparent, and selection_bg to 50% transparent gray. When selection_fg is fully transparent we'll use the normal fg color. When selection_bg is partially (or fully!) transparent, it will be alpha blended over the current cell background color. To support this, the config file will now accept rgba colors specified as 4 whitespace delimited numeric values. If a value ends with `%` it is interpreted as a number in the range 0-100. Otherwise, it is interpreted as a number in the range 0-255. The 4 values are red, green, blue, alpha. At this time, only the selection_fg and selection_bg settings accept alpha values. refs: #1615		2022-02-05 15:17:22 -07:00
