How to get the size of a view programatically

**Is your feature request related to a problem? Please describe.**
We are trying to find a way to get the width and height in PT of each rendered component.

**Describe the solution you'd like**
Maybe exposing those values from the View, Text, Image, etc components would be a valuable.

**Describe alternatives you've considered**
We have tried implementing some HTML with styles similar to the printed pdf size, and converting PX to PT but the value, even though it is close, is not accurate.

**Additional context**
What we really need is to get the same numbers that appear on `debug={true}` so that we can make some decisions depending on the size of the elements.
