Hi,
I started working on World Transforms last night; it seems we got to
about the same stage too - oh well. I think the way to do sheared
arcs / ellipses is to approximate them to Beziers, transform the
control points and draw these - didn't get as far as this either but
it should work. Not sure about bitmaps and such like at all.
Anyway it looks like the scaling in EnumEnhMetaFile is basically
right. It needs to be modified if the MapMode is not initially
MM_TEXT but that's not too hard.
Good luck,
Huw.
