Windows may have a name used while minimized, distinct from the name they display in their titlebar.
Most of the time this is a bad idea from a user interface standpoint. But you can set such a name with this function, if you like.
After calling this with a non-null name, calls to
set_title will not update the icon title.
Using null for name unsets the icon title; further calls to
set_title will again update the icon title as well.
Note that some platforms don't support window icons.
