creating an image with 0px width and 0px height is meaningless. but as you
said, a program should validate user's input and avoid crashing.

why i want to create an image with 0px width and 0px height ? because i have
copied an image into my clipboard. i expect the canvas will autosize to the
actual size of the image when i click ctrl+v in pinta.

so i request a new practical feature:
when open the new image window, the actural size of the image in the
clipboard will be detected.
