TextAnnotations - TextBlocks should have a property for height

[claudiaareneee]

Is your feature request related to a problem? Please describe.

I would like to be able to specify a height around a TextAnnotation similar to how we describe the width.

Describe the solution you'd like

TextBlock should have a property called height with the following attributes

• It should act similar to width. 0 height means the height grows with the text.
• We'd need to figure out which takes priority when a user adds runs to the TextBlock that don't fit in the specified width or height. I propose for simplicities sake, that the height grows, and the width remains the same.
• Also units should be meters
