[metapost] problem with drawoptions and fake Euro symbol

[Stephan Hennig]

Hi Taco,

is it correct that to some degree you agree there is a bug in the
current behaviour?

Ah, it's a property of single text or stroked items, even better!  Let
me add some ideas:

*  I think it should be possible to access this property of an item
within an image via a new, e.g., 'external' primitive in analogy to the
stroked, filled or textual primitives.

*  It should be possible to change that property of an item.  Or there
should be a global internal variable that lets one choose between the
old and the new behaviour.

The latter can be useful when there is material of a picture environment
inside btex..etex.  Admittedly, this is a strange use-case, since why at
all should a picture environment be used from MetaPost?  At least, I
have a strong feeling that user should be able to access and configure
this part of MetaPost.

I'll fix this.
