/* Note: the Undo/redo commands use a "brute" method:
|
||||
* the full page layout is converted to a S expression, and saved as string.
|
||||
* When a previous version is needed, the old string is parsed,
|
||||
* and the description replaces the current desc, just like reading a new file
|
||||
*
|
||||
* This is not optimal from the memory point of view, but:
|
||||
* - the descriptions are never very long (max few thousand of bytes)
|
||||
* - this is very easy to code
