Tooltips consist of three parts; left, center and right. You can see all of them in the texture example above. The width of the texture is 6 pixels, which when divided by 3 (for all three parts) equates to 2 pixels per part.

With that much space, we can create more complex shapes for the borders. Here's an example:
