Pillow and pillowcase volumes are heavily mismatched.

[Aerin-of-the-Toast]

Describe the bug

Pillows have a volume of 1 liter, while pillowcases have a pocket capacity of 15 liters.

Steps To Reproduce

Go into any house in the game or anywhere pillows spawn, pick up a pillowcase that's holding a pillow and notice the volume discrepancy (that the pillow only takes up 1/15th of the pillowcase's max capacity).

Expected behavior

Pillowcases have a difficult time fitting one pillow inside, since they're meant to be more form fitting. In theory, a pillowcase should have a pocket capacity only slightly larger than the volume of a pillow itself. 1L seems far too small for the size of a pillow while 15L seems far too large for the size of a pillowcase; Mark suggested a ballpark of 6-8L for the size of a pillow/the capacity of a pillowcase, which seems much more reasonable.

Spawned a pillow case, and it description says it can contain up to 15L and 15kg with a maximum item length of 353mm.
While I initially thought the volume was to contain a body pillow, it greatly exceeds the volume of one.
Pillow : 1L 0.51kg
Down-filled Pillow: 1L 0.51kg
Body Pillow: 1.75L 0.77kg
