Test pdf, exported from Inkscape

PDF with opacity exported from Inkscape.  Looks OK in PDF viewers.  When LODraw imports there is a black rectangle the size of the entire drawing for each opaque object.  In this example there are 3 such rectangles.  Delete them and only two of the circles remain (not sure why).  This is with 3.4.4 release.

New opacity test (PDF)

To implement PDF opacity features correctly we need to support opacity value setting not only per-object, but also per-group.
Actually, we need masking, but per-group opacity will be good too.
For example, we have 3 circles drawn one on top of each other. Then opacity applied to this group.
Result will differ if we draw one circle with opacity, then draw second circle, then draw third one.
Here are examples in SVG and PDF.
