If a sector uses texture x and texture x has decor lights
defined then there should be a rules system which
governs whether the lights are used.
If Sector A is larger than specified size and ceiling
texture is texture x then don't use lights.
If Sector B is 64x64 and floor texture is teleporter
texture then use effect B rather than effect A.
This same system should be used for particle generators
This system should then only be used for maps that
don't have map effect definitions.
