Add a procedure to create a new image with the defaults from the preferences
Operating System: All
Description of the feature
Creating usable image via the procedures provided by GIMP in e.g. the Script-Fu console can be a tedious process - you have to remember that you need to create an image, and a layer and insert the layer into the image.
It would be nice if there was a procedure which create an image that resembles what you get via File > New with the default images settings as specified in the preferences.
Use cases
Creating self-contained test cases for examining scripting issues are where I encountered this personally, but having a direct equivalent to File > New will likely help any script authors, and be it only with the first steps.
