Unfurl a string
Given a square string, produce all the output for the string at every stage of unfurling.
The string must unfurl in a clockwise direction one quarter turn at a time.

Rules
This is code-golf so the shortest code in bytes wins.
- Any reasonable format can be used for I/O assuming it is consistent.
- Spaces must be used to pad the top lines of the output.
- Must be able to handle input of all printable characters (including space:
\x20-\x7e):
!"#$%&'()*+,-./0123456789:;?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~
- Leading/trailing whitespace is allowed.
- You can assume the string will always be a square.
- All standard loopholes are forbidden.
Inspiration: Write a square program that outputs the number of times it has been "unrolled".
