Aiga Symbols: Dislocated clones

[Hachmann]

The telephone and the elevator icon in the AIGA symbols set use clones with just an x or y position specified.

In Inkscape 0.92, those clones are dislocated, not sure if the problem is now with Inkscape or with the symbols. Clones with transform matrices work normally.

Topic was raised earlier this week on irc by Mc (see attached irc log excerpts).

Note that the issue is exposed in documents which at the time when the first instance of a symbol is inserted into the drawing does use display units other than 'px' (see Document Properties > Page > General > Display units). IIRC symbol scaling on insertion is still based on the display units instead of the document scale.

Based on tests with archived builds (on OS X 10.7.5):
- not reproduced with lp:inkscape rev <= 13852,
- reproduced with lp:inkscape rev >= 13858,
the reported issue seems to have been exposed in commits related to bug #1365451 (comments 17-18).

Likely relevant changelog:

Possibly related commits:
Revision 13853: during copy and paste, scale stock symbols from units of 'px' to 'document-units'.

Revision 13854: allow stroke_width to be scaled even if stroke color is not defined.

(OT: Thank you, V. That log is impressive, the Inkscape project is so lucky to have y'all on board.)
