ターミナルがダサいとモテない。WezTermの背景をUnsplashで変える編。

 -- Linear and Radial gradients are also supported; see the other
 -- examples below
 -- orientation = "Vertical",

 -- strings and more

 -- To avoid vertical color banding for horizontal gradients, the
 -- gradient position is randomly shifted by up to the `noise` value
 -- for each pixel.
 -- Smaller values, or 0, will make bands more prominent.

 -- on a retina macbook pro display.

 -- By default, the gradient smoothly transitions between the colors.
 -- You can adjust the sharpness by specifying the segment_size and

 -- segment_smoothness is how hard the edge is; 0.0 is a hard edge,
 -- 1.0 is a soft edge.
