In later versions of View, but (instead of button) produces a rounded
button sized to the text unless you over-ride it's size (I think).

>> ? size-text
USAGE:
SIZE-TEXT face
DESCRIPTION:
Returns the size of the text in a face.
SIZE-TEXT is a native value.
ARGUMENTS:
face -- (Type: object)
So...
>> layout [t: text "hello"]
>> size-text t
== 25x12
