What is the use of the "msapplication-TileImage" meta tag?

Question

I have come across the following code:

<meta name="msapplication-TileColor" content="#113228">
<meta name="msapplication-TileImage" content="icon-tile.png">

Could someone please explain what those meta tags are used for? I can't find any documentation about those tags.
