[NTG-context] Metafun : reuse a static picture

[Fabrice L]

Dear list,

	I have some difficulty to reuse a static picture in a multipage MetaFun document. I wish to define a complex image, with graphic and texts, and manipulate this image at each page. As the minimal working example shows, if I define a particular picture in the variable « AnImage » and a random text in another picture called « AnotherImage », I can use these two pictures in the first page of the document, but only one of them appears in the second page of the document (with the same code). I know that if I replace startMPinclusions/stopMPinclusions by startMPinitializations/stopMPinitializations, this works, but the image is recalculated (a different number is drawn), and I do not want this since the image is complex and takes time to make. 

	So the question : how to make the two pictures « AnImage » and « AnotherImage » appears in the both page ?
	Thanks for any help !
	Fabrice,

% MWE :
% 8< ---------------------------------------
\starttext

\startMPinclusions
	picture AnImage , AnotherImage;
	AnImage := image (
	  draw fullcircle scaled 40;
	);
	AnotherImage := image (
	  arandomnumber := uniformdeviate(1);
	  draw textext(decimal(arandomnumber)) scaled 0.5;
	);
\stopMPinclusions

\startMPpage
	draw AnImage ;
	draw AnotherImage ;
\stopMPpage

\startMPpage
	draw AnImage ;
	draw AnotherImage ;
\stopMPpage
\stoptext
% 8< ---------------------------------------
