 which count currently used shape key values of armature mesh when transfer)
 
 Limitations and new delta option for 2.8
 - Target mesh may not have any transformation at object level,
   it will be set to zero.
-

 - new "delta" option usage, when you hope to make new shape-key with keep currently visible other shape keys value.
  it can generate new shape key, with value as 1.00. then deform target shape as source shape with keep other shape key values relative.
