* This is similar to GtkLabel but clips itself and displays '...' if it
* can't fit inside its allocated area. The intended use is for inside buttons
* that are a fixed size. The GtkLabel would normally display only the middle
* part of the text, which doesn't look very good. This only supports one line
* of text (so no wrapping/justification), without underlined characters.
