[jbosstools-issues] [JBoss JIRA] Updated: (JBIDE-4895) Provide a better algorithm for drawing mapping diagrams

[Yahor Radtsevich (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBIDE-4895?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yahor Radtsevich updated JBIDE-4895:
------------------------------------

    Description: 
Current mapping diagram drawing algorithm seems to be almost random (see 3.1.0.M3_drawing-1.png).

A better algorithm should:
1. Never cross tables with lines.
2. Draw as few line crossings as possible.
3. Draw tables closer if they have more constraints.
