How can one obtain the size (width and height) of some text?

I've been reading the code trying to figure out how to get the width and height of a LaTeX string rendered using MathTeXEngine, but I haven't been able to figure it out. To be more precise, I was able to do it for the width, but no the height. The goal was to get a bounding box with the coordinates of where the text was contained.

Every TeXElement has the methods

leftinkbound
rightinkbound
bottominkbound
topinkbound
inkwidth
inkheight

so there are currently two ways to do it.

1. With the result of generate_tex_elements, take the minimum/maximum over the elements e.g. maximum(topinkbound.(elements)) and get the width/height from it.
2. Intercepting the overall Group before it get unravelled into a list ( see

   MathTeXEngine.jl/src/engine/layout.jl

   Line 281 in 8772952

   function generate_tex_elements(str, font_family=FontFamily())

   ). tex_layout returns a single Group on which inkwidth or inkheight can be used, and can then be unraveled to get a flat list of elements.

In any case, I should probably provide such bounding box function for the list returned by generate_tex_elements.

Thanks a lot! I was able to come up with the bounding box function I wanted.
