Summary	0001021: pens in metapost stop working after clipping is used
Description	With ConTeXt ver: 2020.03.10 14:44 MKIV beta fmt: 2020.7.20 with mplib v2.20.5 the following happens: After a clipping mask is used, pens stop changing thicknesses. This didn't happen in earlier versions of ConTeXt, nor does it happen with LuaLaTeX with the same mplib.
Steps To Reproduce	\starttext \startMPcode picture p; p := image(draw (0, 0)--(1cm, 1cm) withpen pencircle scaled 1cm;); clip p to (unitsquare shifted (-1/2, -1/2) scaled 10 cm); %this one draw p; draw (0, 0)--(-1cm, 1cm) withpen pencircle scaled 1cm; \stopMPcode \stoptext produces a picture with one thick line and one thin line (bug.png), while \starttext \startMPcode picture p; p := image(draw (0, 0)--(1cm, 1cm) withpen pencircle scaled 1cm;); draw p; draw (0, 0)--(-1cm, 1cm) withpen pencircle scaled 1cm; \stopMPcode \stoptext produces two thick lines as intended (nobug.png)

Hans Hagen 2020-07-21 17:24 manager ~0001730	fixed in next version (of context) best report this to the context list or in the context tracker because usually something like this doesn't relate to luatex (where mplib doesn't change) or lualatex / plain (which uses different code)

Hans Hagen 2020-07-21 17:24 manager ~0001731	fixed in context, no luatex change needed
