Reactions in JSME, position and zoom in / out

[lpatiny]

We have various problem with drawing reactions, zoom in / out and having many products.

1. When we move a reagent so that it becomes a product no event is generate and we are not aware of the change of its status

2. When we have many reagent and products JSME always put them one one line. It would be nice that the coordinates are kept so that we can dispose them also vertically

3. When we zoom in / out and draw molecules the coordinates may become unexpected

Reactions in JSME are not as much used and tested as compounds. Bugs and issues have been fixed in reaction handling. Unfortunately, not all issues described above have been fixed.

From the release notes file:

JSME 2017-06-18

• RXN export agents (non standard format)
• RXN export format new option: merge reaction component
• when a reaction role is changed, an event is generated
• setting atom maps for reactions is easier with mouse clicks
• bug fix: applet resize will keep the reaction components around the reaction arrow
• bug fix: paste a reaction when the molecular area scale is different than 1
• bug fix: if the molecular area scale is different than 1, the reaction role of the reaction components were not correctly reported
