[Gimp-user] Any way to resize all the layers in an xcf file to fit the canvas?

[Elle Stone <ellestone ninedegreesbelow com>]

Hi All,

Of course all the layers can be resized one by one to fit the canvas. 
But I've been doing a *lot* of rearranging/moving of different groups of 
layers, and clicking on each layer one by one to resize it is rather 
time-consuming and involves a lot of clicking. Right now that's 17 
layers and four groups.

Is there a magic command, or maybe an easy script that can be run to 
resize all the layers to fit the canvas, all at once?

Also, does the layer mask resize when the layer is resized?

In case it matters, I'm using GIMP 2.9.8 on Linux.

Best,
Elle
