btex/etex is better replaced by textext().

Nevertheless, this does not change anything. Context intercepts and 
replaces textext() (and btex/etex) during processing. It does not return 
a picture but a text bounding box that gets substituted upon shipping out.

You *can* save your text to a string, to be passed to textext() in your 
MP macros.
