If default is background color of the frame then it means that cut out
rectangle is transparent, there shall be no color.

However, using default background for images related to frame is very
bad idea. People use various themes and theme of Emacs is not related
to the image.

By default you should have background color to be white and
customizable.

Follow the established standard that foreground and background for
image editing shall be defined somewhere beforehand just as in Gimp.

That is very useful, not marginal, that is what we do with images. We
cut out something in order to save it.

There shall be cut and copy options, not just cut. 

Copy means to select and copy, without removing part of the image.
