Base Separation

[ThePotatoGuy]

#4458 #4474

Key Changes

• all non-bg sprites updated to new night filters
• arms, mouths, eyes, nose and other sprites remade
• sprite-system updated to work with the new split base system
• expansion of unit test framework with additional types
• ACS are now forced to be worn at their recommended layer
• tears left/right officially removed

Split-Base system

• Body sprites are now split into 2 pieces: back (0) and front (1).
• Arms are also split into back (0) and front (1).
• Clothes and base sprites are no longer baked together.
• Base sprites are included now and rendered below clothes
• Additional ACS layers have been added, including ACS layers specifically for inserting ACS between clothes and base.

For a more in depth description of this, check #3174 .

MASPoseArms

New class that represents a pose's arms. Allows for easier pose creation (aka now we can mix and match arms, provided they are separate).
See sprite-chart.rpy for more info.

Remade sprites + new night filtesr

• leaning arms have been redrawn (@Orcaramelo)
• mouths/eyes/nose expressions have been redrawn (@velius94 + @professor-jmo)
• new night filter that doesn't destroy blues and greens (@Orcaramelo)

Unit Test expansion

• assertDictEqual and assertListEqual have been added
• assertEqual now triages to assertDictEqual and assertListEqual if necessary

Sprite JSON updates:

(wiki will be updated with new documentation shortly) (See here for a draft)

Removals:

• fallback - mpm_type should be used to denote a fallback-style MASPoseMap (see below)

Additions:

• mpm_type - new property for MASPoseMap that determines what the values should be. This is only used to differentiate between the Enable/disable and fallback modes.
• arm_split - new property for ACS sprites, contains a MASPoseMap with special string values to determine if an ACS has images for specific split layers. This is only meant for BSE_ACS and ASE_ACS layers.
• pose_arms - new property for clothes sprites, contains a MASPoseMap with MASPoseArms. Determines which layers have arm layers (if at all) for an outfit.
• version - top-level required property. Initial version is 2. This will be updated whenever the sprite system changes format in a way where existing JSONs will be broken. JSONs with a different version are not loaded.

Followups

These will be linked to this PR when they are created:

• soft eyes by JMO
• scold pose ([Suggestion]: Good serious moment/scolding pose #4304) (restleftpointright + down)
• a ton of spritepacks

Testing

• verify all sprites look ok
• verify all sprites night versions are with the new filter
• verify existing spritepacks still load (using the included updated JSONs)
• verify necklace and bracelet still look okay (only ACS in ASE/BSE layers)
• verify trying to wear an acs in the wrong layer (using monika_chr.wear_acs_in or sister functions) will force the acs to be worn in the correct layer. (this can be overrided if needed)

Unit Tests

Verify the 3 new groups are sucessful:

• JSON - MASPoseMap
• JSON - MASPoseArms
• JSON - MASPoseArms-JGroup
