# and an image (e.g. breeze) which will be used to show a screenshot.
# Themes with no image get a "missing screenshot" image; if the
# Themes with no image set at all get a "missing screenshot" image; if the
# image file is not found, they get a color swatch based on the image name.
#
# Valid forms of entries in the *themes* key:
# - A single string (unquoted), which is the theme id
# - A pair of *theme* and *image* keys, e.g.
# ```
# - theme: fluffy-bunny.desktop
# image: "fluffy-screenshot.png"
# ```
#
# The image screenshot is resized to 12x8 the current font size, with
# a minimum of 120x80 pixels. This allows the screenshot to scale up
# on HiDPI displays where the fonts are larger (in pixels).
