Ceilingstat
Ceilingstat is a sector-structure member similar to cstat, as it is a bitfield.
The known values are below:
- 1 = Bit 0: Ceiling is a parallax sky/texture
 - 2 = Bit 1: Ceiling is sloped
 - 4 = Bit 2: Ceiling Texture's x & y is swapped
 - 8 = Bit 3: Ceiling Texture Expansion is on ["E" key in Build/Mapster32]
 - 16 = Bit 4: Ceiling Texture's x is flipped
 - 32 = Bit 5: Ceiling Texture's y is flipped
 - 64 = Bit 6: Ceiling Texture Relativity is on ["R" key in Build/Mapster32]
 
- 128 = Bit 7: Masked Ceiling (different from being clear only for TROR-extended ceilings)
 - 256 = Bit 8: Translucent Masked Ceiling
 - 384 = Bit 7&8: Reverse Translucent Masked Ceiling
