Note:

Different toolkits behave differently with this function.

As a general example if you supply width and height size as 32x32px QT5
will paint an option image 32x32px in size but GTK3 will only paint an
image of 16x16px inside a 32x32 frame regardless of what size you request.

To get a truly different size Option image with gtk3 you must paint the
16x16 Option and then stretch the image.
