DESCRIPTION
The extbutton extends the behavior of the atomic Tk button by allowing text and an image or bitmap to coexist. The user may use the -image
or -bitmap options to specify an image as well as the -imagepos option to specify image position relative to the text. Note that the
extbutton is not intended to be used without an image/bitmap. There will be an emtpy space next to the text if no image/bitmap is speci-
fied.
