That's what she said

Ok, I just did that for symettry.

|-------|     ---------
|   A   |     |   A   |
|-------| OR  |-------|
| B | C |     | B | C |
|_______|     |_______|

IMO these both look a bit silly (right one lookslike bed. left one looks
like a house/owl/optimus prime face), this is biggest plus with using plus.


Transpose

+-------+     +-------+
|   A   |     |   | B |
|-------| --> | A |---|
| B | C |     |   | C |
+-------+     +-------+

Rotate clockwise

+-------+     +-------+
|   A   |     | B |   |
|-------| --> |---| A |
| B | C |     | C |   |
+-------+     +-------+

anticlockwise

+-------+     +-------+
|   A   |     |   | C |
|-------| --> | A |---|
| B | C |     |   | B |
+-------+     +-------+

Flip horizontal

+-------+     +-------+
|   A   |     |   A   |
|-------| --> |-------|
| B | C |     | C | B |
+-------+     +-------+

Flip verticlly

+-------+     +-------+
|   A   |     | B | C |
|-------| --> |-------|
| B | C |     |   A   |
+-------+     +-------+

Rotate

+-------+     +-------+
|   A   |     |   C   |
|-------| --> |-------|
| B | C |     | A | B |
+-------+     +-------+

rotate back

+-------+     +-------+
|   A   |     |   B   |
|-------| --> |-------|
| B | C |     | C | A |
+-------+     +-------+

BTW what kind of transofmration would occur, if you had window tree like

(nil W1 (t W2 W3 W4))
and you transform it to (flip the tree):
(nil W4 (t W3 W2 W1))

Hard to imagine, could potetnially be another useful thing.
