@function HIURLTextViewCreate
@abstract Creates a new URLTextView object.
@discussion A URLTextView displays a static text item with an associated URL using a browser-style
appearance; the text is drawn in blue, and underlined. When clicked, the view tracks the
mouse until the mouse is released, and the view uses LaunchServices to open the URL
associated with the view.
The view has two primary attributes: its URL and its text. At least one of these must
be specified for the view to draw any content. If only the URL is specified, then the
view draws the URL's display name, if available, or the URL itself (minus scheme) as
its content. The view client may also specify the view's text separately, which is drawn
instead of the URL; for example, the client might specify "http://www.mycompany.com" for
the URL, and "MyCompany home page" for the text.
@param inBounds
Bounds for the control. These are in coordinates relative to the view in which this
view will be embedded.
@param inURL
The control's URL. May be NULL.
@param inText
The control's text. May be NULL. If no text is specified, the URL's text is used instead.
@param outURLTextView
On exit, contains the new control.
