[NTG-context] linear_shade not working any more

[Mojca Miklavec]

Hello,

It seems to me that the following code worked in some beta 2 weeks ago:

\setupcolors
	[state=start]
\definecolor
	[BgColor1]
	[white]
\definecolor
	[BgColor2]
	[r=0.7,g=0.7,b=1]

\starttext
\startMPcode
	path p; p := unitsquare scaled 3cm;
	linear_shade(p,0,\MPcolor{BgColor2},\MPcolor{BgColor1});
\stopMPcode
\stoptext

But with 2006.07.14 I get:

This is MetaPost, Version 0.901 (Web2c 7.5.3)
(shading-mpgraph.mp
>> (1,0,0)
! Isolated expression.

                   ;
scaledgray->begingroup.red;
                           endgroup
l.286 ...(scaledrgb(0.7,0.7,1,1)),(scaledgray(1,1)
                                                  ));
?

Any suggestions about what could go wrong?

Thank you,
    Mojca
