The renderers for these are RenderMenuList and RenderListBox. And the  
menu is PopupMenu. You can find the code in those source files and see  
what comes from the theme. For example for RenderMenuList it's some  
functions that provide internal padding and a minimum list size. And  
in RenderListBox it's some colors that come from the theme.
