Checked in 1.10.5.0, seems working
No Changes

Made Limb DamageOverlay (aka bloody limb sprite) appear earlier

Added float [0,1] DamageOverlayThreshold setting, it's % of bleeding on which damageOverlay is fully opaque, vanilla value is 1.0

Changed DamageOverlayThreshold from 1.0 -> 0.3

Added "Blood decals lifetime" slider
Added cleaning

Added blood splashes from direct damage like bullet impacts / spears/ swords etc

Hid vanilla blood, added slider to setting menu

Reworked config, added more stuff for debug

Also removed decals from showperf because it's not the main lag source

Added xml config and xml decal prefabs
They are in mod folder
reloadbloodconfig - reloads config
resetbloodconfig - reset to default
reloadbloodprefabs - reload decal prefabs
reloadblood - both
printbloodprefabs - for debug
printbloodconfig - for debug
bleed - get 100 bleeding on right hand
