Preview generation for layer groups is more expensive than for
other types of drawables, mostly since we can't currently generate
layer-group previews asynchronously. Add a preferences option for
enabling layer-group previews separately from the rest of the
layer/channel previews; both of these options are enabled by
default. This can be desirable regardless of performance
considerations, since it makes layer groups easily distinguishable
from ordinary layers.
