Eclipse Kepler RCP CoolBar Actions CSS

问题

Similar to this question's screenshot, my RCP App has those annoying spaces between actions on the coolbar. My guess is that it's because I'm using deprecated extensions in the plugin.xml (i.e. ~~viewActions~~ actionSets).

For now, I don't want to begin changing all those action implementations to comply with the new rules (mostly because there are A LOT of those actions).

Question: Can I somehow apply CSS styling to that CoolBar so that extra spaces are grabbed by the actions?

The road so far:

NO e4 STUFF! This question does not satisfy mine.
My other (similar) question. Feel free to complete that guy's answer.
RAP CSS - does this apply to RCP as well?

Looking at the debug plugin which does align the toolbar entries correctly it first defines a toolbar like this:

<extension 
     point="org.eclipse.ui.menus">
  <menuContribution
         locationURI="toolbar:org.eclipse.ui.main.toolbar?after=additions">
      <toolbar
            id="org.eclipse.debug.ui.main.toolbar"
            label="%DebugActionSet.label">
         <separator
               name="breakpointGroup"
               visible="true">
         </separator>
         <separator
               name="threadGroup"
               visible="true">
         </separator>
         <separator
               name="stepGroup">
         </separator>
         <separator
               name="stepIntoGroup">
         </separator>
         <separator
               name="stepOverGroup">
         </separator>
         <separator
               name="stepReturnGroup">
         </separator>
         <separator
               name="emptyStepGroup">
         </separator>
         <separator
               name="renderGroup"
               visible="true">
         </separator>
      </toolbar>
   </menuContribution>

and then in the actionSet references the defined toolbar:

      <action
           toolbarPath="org.eclipse.debug.ui.main.toolbar/breakpointGroup"
           ... other stuff ...
           id="org.eclipse.debug.ui.actions.SkipAllBreakpoints">
     </action>
