Current "we take things for granted these days" discovery: QuickDraw doesn't have a way to rotate stuff.
If you want to rotate a PICT 180°, you either have to rasterise it offscreen and read the pixels back in reverse, or you can try using a “picture comment" to get the _printer_ to apply the operation.
And "it is impossible to determine which picture comments are supported by the driver of the current printer”. Helpful.
