It is a PDF in a MS-Word doc, gets read by us as Metafile. This has 5 actions, containing the graphic stuff as single Bitmap. With the Bitmap now embedded as primitive, it gets painted by the system renderers. Also before this should have happened, but maybe this was still painted using the old vcl self-scaling. In fist case, AA is the sdame, in the 2nd it will be better. Checked with LO52 - for me it looks quite the same, slightly better. Also the Zoom/scroll will now be much better. More an enhancement.
Checked and as I thought, problem is writer is not using primitives (yet) to paint that content, this needs to be enhanced.
Have adapted to let writer use primitive rendering. This is the prerequisite to use the VectorData available. For now, this will fallback to VclProcessor2D::RenderMetafilePrimitive2D and thus use the direct renderer again wich we try to get rid of, but this is needed for fallback quality to the current state of things, so slowlyness and speed/hang/crash on zoom will be back for a (hopefully short) while. I checked that all this is much better with the fully activated emfplus stuff.
All tasks have this same reason, so all others are double to this one.

fix done and in master, building locally to do a 2nd check
Allright, now we have this ficed and the EMF+ activated - all much faster and better quality. Faster in EditView (zoom, panning) and faster and much better quality in e.g. PDF export.
