stage-view: Add API to inhibit cursor overlay painting

Browse Source 
This adds some plumbing to get the "default" paint flags for regular
stage painting, where one either wants to paint the overlay, or not.

If inhibited, the 'no-cursors' paint flag is used, otherwise the 'none'
flag. This will be used to allow having a per stage view hw cursor
state.
