Hi,
I'd like to scale something (actually a symbol drawn in TikZ) to the exact
high of the char 'M'. I found the scale environment for it but struggle to
measure the correct font height. I found the "definemeasure/measure/measured"
commands but they define a dimension and are not for doing measurements on
rendered text. Is there a simple way to get the height a char as a dimension?
MWE:
```
\starttext
% Is it possible to replace 1cm with a common expression?
This is the letter M. \scale[height=1cm]{a} should have the exact same size as
M.
This should also be true {\tfc with a bigger M. \scale[height=1cm]{a}}.
\stoptext
\the\dimexpr\fontcharht\font`M+\fontchardp\font`M\relax
