This operator initializes mask values for the entire mesh. It supports
different modes for initializing those values, and more will be added in
the future.
The initial version supports generating a random mask per vertex, Face
Sets or loose parts. These masks are useful for introducing variations
in the model using the filters (both shapes and colors).
