Tool tip resizing - should be opt-in ?

(http://bugs.adobe.com/jira/browse/SDK-19578?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel)

Not with standing it's taken 6 months for anyone to notice this needs to be an opt-in feature (I personally think, even in a 3D layout, tool tips should be scaled, even to very small sizes), how do people think this should be handled ?

Any sensible implementation is going to mean altering IToolTipManager, right, to add something like either 'miniumScaleSize:Number=0.1' or 'scaleToolTips:Boolean=false' ?

http://bugs.adobe.com/jira/browse/FLEXDMV-2048 suggests I should probably be adding a new method to that interface *anyway*, but I feel I might now be touching a *lot* more stuff than I could do. I've no checked, but are there any (many) alternative IToolTipManager implementations I would break ?
