"""This file provides support for rectangle-mode in an editor.
In particular, it is possible to select a rectangular area,
cut it, and paste it elsewhere.
To perform a selection, use the standard selection mechanisms (e.g.
mouse+click selection, or keyboard shift+arrows).
The highlighting of the selection itself is done on the whole
lines, not on the rectangle itself, but the rectangle is the
part between the column of the start of the selection, and the
column of the end of the selection. For instance:
ABCD
EFGH
IJKL
If the selection goes from B to K, the rectangle will be:
BC
FG
JK
However, the highlighting will include:
BCD
EFGH
IJK
Cutting the rectangle will result in:
AD
EH
IL
If you move the cursor before "A", and paste the rectangle:
BCAD
FGEH
JKIL
