we can have strut but also think of enforcing ht / dp
(or we can have minima but that i'd rather add some options to the
engine - we already have some but i never came to apply them yet)

I don’t get the layer in the TEXpage.
How could I get it with the TEXpage dimensions?
only by first boxing (using framed or so) and then taking those dimensions
Many thanks for your reply, Hans.
I’m afraid I don’t know how to make the commands work:
\setupexternalfigures[location=default]
\definelayer[hi]
[x=.5\dimexpr\framedwidth\relax, y=.5\dimexpr\framedheight\relax]
\setupbackgrounds[page][background={foreground, hi}]
\starttext
\startTEXpage
\framed[frame=off, offset=none]
{\setlayer[hi]{\color[red]{hi}}
\externalfigure[cow-brown]\framedheight}
\stopTEXpage
\stoptext
In this case, \getfiguredimensions would work, but I don’t know how to
deal with a pure text box.
BTW, is there a way to have TEXpages numbered? "pagestate=start" seems
not to work here.
for the wiki ...
\starttext
\definelayer[hi]
\startTEXpage[background=hi]
\setbox\scratchbox\hbox\framed
[frame=off,offset=none,align=middle]
{\input{tufte}}%
\setuplayer
[hi]
[width=\wd\scratchbox,height=\htdp\scratchbox]
\setlayer
[hi][preset=middle]
{\color[green]{there}}
\box\scratchbox
\stopTEXpage
\defineoverlay[hi]
\startTEXpage[background=hi]
\defineoverlay

Re: [NTG-context] Unicode normalization and Hebrew in ConTeXt
On 8/17/2021 9:46 PM, Joey McCollum wrote: Thankfully, it looks like this was just a problem with my implementation of the OpenType feature and not with ConTeXt's handling of it! (I worried that it might be ConTeXt when I saw that XeLaTeX was handing the feature correctly.) Hans graciously helped me identify the problem, and everything looks good now! Just for the record: one can best try to make a font as robust as possible and not rely on side effects (ambiguous cases). When Idris and I tested some shapers we found that there can be inconsistent results (fwiw, in a rather complex font context agreed more often with uniscribe than xetex, but in the end on ehas to make the font okay for all i guess). When we started with opentype (luatex showed up in 2005) we took uniscribe as reference so that is our benchmark. And lack of specs made us figure out things stepwise. Now, if something works in one shaper and not in another it can of course be due to bugs but it can also be that the spec is simply fuzzy and choices have been made. There is then the danger that eventually bugs become features (I assume the amount of leverage matters here, and tex has zero) which then settles it (kind of) but that doesn't man that one should gamble on it. The same is true for fontnames: don't rely too much on the heuristics hard coded in programs (e.g. fontforge has some for font names, properties, glyph names, and although that is nice for recovery, it also makes other usage hard because fighting fuzzy heuristics is hard once information is lost). Btw, a side effect of your 'issue' is that I found a way to save some memory for some fonts (for now only in lmtx) at the cost of hopefully little extra runtime.
