\ht\Content=\currentlayerheight%
\dp\Content=0pt%

the point is that on minimals-beta there is an error,
on minimals no , but xpdf says
Error: ExtGState 'Tr0' is unknown
Error: ExtGState 'Tr0' is unknown
Error: ExtGState 'Tr0' is unknown
Error: ExtGState 'Tr0' is unknown
Error: ExtGState 'Tr0' is unknown
The code is not wrong -- maybe a bit strange
Also this is ok in minimals
fails in minimals-beta,
and I think It's legal code, but I can fail .
\newdimen\currentlayerheight
\starttext
\currentlayerheight=\dimexpr 12pt +0pt\relax%
\the\currentlayerheight
\stoptex\newdimen\currentlayerheight
