StickUVW
If a texture projection operator is reading from somewhere above
the Modeling region, StickUVW changes the texture projection
operator to read from the top of the Modeling stack (so that UVs
are computed after modeling deforms but before shape animation or
enveloping). Textures using these coordinates will appear to stick
as the object is deformed by shape animation or enveloping.
StickUVW takes a list of objects and UV properties (texture
projections) as input. If an object is a primitive, such as a mesh
or a NURBS surface, the command changes the current UV properties
used by the materials (see Material.CurrentUV) assigned
to the object. If a texture projection does not have an operator
(because the operator was frozen), the command has no effect.
