OK, I should have pointed (sorry) out that XLPTODP will need both x
and y in order to calculate the x' . So obviously the functions will
change a little. Of course you could just use LPToDP but this will be
slower and less convenient.

Also look at PATH_DoArcPart in graphics/path.c [I didn't write this so
I don't know what the algo is...]

So should MM_HIENGLISH change too?

OK, I'll let you get on with it.
