Polymer rendering breaks in new version

Hi,

We are writing from ChEBI(www.ebi.ac.uk/chebi). Thank you so much for such a
wonderful toolkit. The new version is kind of breaking the polymers as you can see below

Ketcher | New Version | Old Version
------------ | ------------- | -------------
Ketcher (all good) |com.epam.indigo - 1.3.0beta.r16 | com.ggasoftware.indigo - 1.1.12
 |  |

- In the old version, n is on the wrong side (and too small) but brackets are fine. Whereas in the new version n (still too small) has been fixed to the right side but brackets are poorly sized and poorly positioned - they interfere with the structure. They should cut through the center of the bond.
- I also would like to bring an attention again about the cross double bond and the thickened single bond (which I have reported in the google groups)

Ketcher seems to be fine in all the cases ...

Thanks,
Venkat
