Autoselect option on export image
When exporting images, especially with "Layers as seperate files", it would be awesome to have an additional option, that each layer only exports the visible area and no the complete size.
E.g. created a ship with several layers, body-layer, cockpit-1-layer, cockpit-2, cockpit-3, ... each cockpit has a different size. I only want to export the visible pixels of the cockpit, without empty pixels around.
