[eclipse-pmc] API change request: Deprecated API removal

[Carolyn MacLeod <Carolyn_MacLeod@xxxxxxxxxx>]

The following method was added after 3.2 and is no
longer needed:
org.eclipse.swt.widgets.Control.dragDetect(int, int, int, int)

It was deprecated but we left it in so as not to burn M6.
Request for permission to delete it now.

GOALS/BENEFITS:
Avoid growing API with an unneeded method.

CORRESPONDING BUG:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=170849

RISKS:
No risk since this method didn't exist in 3.2 and we checked that no
references to this method exist in the Eclipse SDK.

PERFORMANCE IMPACTS:
None.
