Hey---
I'm trying to insert outlined text (derived from MetaFun example code) into a document and it seems to work up to the point that the text has depth (descenders). There's a previous post that mentions using textcommand for titles to ensure that the appropriate
baseline is used but I haven't figured out why that would work; for my purposes, I'm insert the text inline so that solution wouldn't work here. I have included a MWE that demonstrates the problem; I've tried putting both the text and the outlined text in
a box, then adjusting the outlined text by the depth of the text itself but that doesn't seem to work. I expect that there's an easy way either in MP or ConTeXt, but I haven't found it yet.

(Here is the code with my attemps to shift the baseline; the \dp & \wd approach seems to do nothing, and the \lower doesn't compile and I haven't pursued why yet.)

Any feedback or suggestions would be appreciated.
