When the render dialog is done, the dialog could show a
Show in File Manager button. It could stay in the bottom-left corner, for example, but people in IRC #gnome-design GimpNet should be asked if this is the best option. When clicked, it should work like Shotwell's button: opens the folder and selects the file.
This is useful for: inspecting the file, opening it, dragging it to a browser window to upload.
