Hi Marco, great you're making progress -
you asked:

Yep.

XShape is an interface, SdrObject the actual representation of that
model - it is facaded towards XShape via SvxShape.

It's like a Windows Metafile (WMF) - a list of "drawing" actions,
recorded from rendering that shape. MetaActions are the atomic
drawing primitives, i.e. set a color, draw a polygon, render some
text etc.

Yep, that's sadly missing documentation - would be wonderful if you
could add doxygen-style inline documentation to the header files,
whenever you encounter such omissions. In this case, it's a
conversion between coordinate systems (see vcl/outdev.hxx for the
prototypes): rSize100thmm is converted from the "MAP_100TH_MM"
coordinate system (i.e. one unit is a hundreth of a millimeter) to
the aMapMode coordinate system.

What's your concrete question? ;)
