Add Size(width, height) as named argument to Caption()

[jthi]

What inspired this wish list request? 

Utilizing Caption in some scripts to relay information to user and not being able to resize "forcing" me to go back to new window as it is difficult to fit text to the very small caption box.

What is the improvement you would like to see? 

I would like to see Size parameter on Caption Box

Caption(
	{100, 200},
	"explanation",
	Size(600, 600),
	Font("Arial Black"),
	Font Size(16),
	Text Color("blue"),
	Back Color("yellow"),
	Spoken(1)
);

Syntax: y = Caption( <{h, v}>, text | remove, <Size(width, height)>, <Delayed( seconds )>, <Font(font)>, <Font Size(size)>, <Text Color(color)>, <Back Color(color)>, <Spoken(bool)> )

Why is this idea important? 

Makes it easier to utilize Caption in different applications.

Could also be nice to add "_" to it so we could minimize it. I would hope that Caption() would be able to remember that so user could hide it if they wish to and it won't appear back unless it is closed first.
