fix the difference of DefaultLayer and Layer

- DefaultLayer has it's own size which is same as stage's
- Added Layer has zero size and top-left parent origin so this causes different
  behavior when user adds Views under the newly created Layer
- make same layouting behavior for both of DefaultLayer and Layer
