Since the affected bundle is to be moved to PDE, I propose to reapply this change to PDE once the move is completed:

• Remove SWT spies #2089
• Migrate swt spies to pde eclipse-pde/eclipse.pde#1746

The spies are now here:

https://github.com/eclipse-pde/eclipse.pde/tree/master/ui/org.eclipse.swt.tools.spies

[laeubi]

Spies are now removed from this repository:

#2089

Replaced by:

• Add SVGs to org.eclipse.swt.tools.spies eclipse-pde/eclipse.pde#1762
