MetaPost shading broken with latest beta

MetaPost shading broken with latest beta

[Adam Reviczky]

Hi,

Using the shading function in a metapost image the whole page is
filled in instead of the figure that defines it.

Minimal example as from the metafun manual 8.3.3
(http://www.pragma-ade.nl/general/manuals/metafun-p.pdf):
\starttext
\startMPcode
fill fullsquare xyscaled (1cm,1cm)
withshademethod "linear"
withshadevector (1,0)
withshadecolors (darkred,darkgreen)
;
\stopMPcode
\stoptext

ConTeXt  ver: 2018.06.23 12:12 MKIV beta  fmt: 2018.6.23  int: english/english
luatex version 1.09 with functionality level 6823,
MetaPost 2.00

With this, I get a full A4 page with the shading colors.
This worked until the beta 2018-06-22 16:02 and the desired output is
shown when using live.contextgarden.net.

Thanks,
Adam

fixed a next beta ... this relates to the context mp inclusion handler 
now following a one-pass approach (again experimental and only > 1.08)

Even in the previous
mtx-context     | current version: 2018.06.22 15:55
I get a full A4 page with the shading colors if I use
Luatex 1.09.0
Development id: 6823

The desired output is obtained if I use
Luatex 1.08.0
Development id: 6731

So I think the latest experimental binary is problematic
in this example.

Best,
Akira
