abcd.aseprite: Indexed, 32x32, four layers ("a", "b", "c", "d")
1empty3.aseprite: RGB, 32x32, two layers ("fg", "bg"), 2nd frame
completelly empty, two tags ("a", "b")
groups2.aseprite: Indexed, 8x8, two groups ("items", "player"),
two layers per group ("items/gun", "items/sword", "player/head",
"player/body"), with one layer hidden ("items/gun").
groups3abc.aseprite: RGB, 9x11, three groups ("a", "b", "c"), with
three layers each one (called "a", "b", "c" too). There is a
combination of visibilities ("b/b", "c", "c/a", and "c/b" are
hidden).
bg-index-3.aseprite: Indexed, 4x4, two layers ("fg" and "bg")
with a special transparent index color (= palette index 3).
tags3.aseprite: 3 tags ("forward", "reverse", "pingpong") and 3
layers ("a", "b", "c"), 4x4, several linked cels + layer "c" with
empty cels.
point4frames.aseprite: Indexed, 4 frames, 2 layers, same cel
content but different positions, can be used to test
-merge-duplicates to check if all cels go to the same sprite sheet
position.
point2frames.aseprite: Indexed, 2 frames, 1 layer, same cel
content as in point4frames.aseprite. Useful to test if
"sourceSize" is different when two cels from different sprites are
merged in the same texture atlas.
2f-index-3x3.aseprite: Indexed, 2 frames, 1 layer, mask color set
to index 21.
file-tests-props.aseprite: Indexed, 64x64, 6 frames, 4 layers (one
of them is a tilemap), 13 cels, 1 tag.
slices-moving.aseprite: Indexed, 4x4, 1 linked cel in 4 frames,
background layer, 1 slice with 4 keyframes (each keyframe with a
different position/size).
