[NTG-context] Label in externalfigures

[Jan-Erik Hägglöf]

I’ve tested this but it appears outside, not as an layer over the picture.

\startMPcode 
draw lmt_svg [
	filename = "steguppgift.svg",
	height = 5cm,
	width = 10cm,
	] ;
label(\sometxt{5,0m},(63.936298,129.563995));
label(\sometxt{37°},(95.652702,27.367201));	
\stopMPcode

Thanks
