Like for the chemistry module, this can be confusing.

Also, sx=,sy= muck with the aspect ratio, don't they?

As we know, there is also an inconsistency in the handling of figure scaling. Consider:

\startMPcode draw externalfigure("cow") xsized 5cm ; draw rawtextext("\externalfigure[cow]") xsized 5cm ; draw rawtextext("\externalfigure[cow][width=5cm]") ; \stopMPcode

The first will draw a distorted, square 5cmX5cm cow, The second and third will both draw an undistorted, rectangular 5cmX3.635cm cow.

indeed but that has to do with compatibility ...

which assume different default dpi. Can this be normalized in the case of file formats (such as pdf) that do not explicitly set the dpi?
