Ok, I understand the benefits for documentation and consistency.

I propose these functions:

qaddItem: layer$addLayer
qdeviceTransform: layer$deviceTransform(event)
q(row,col)Stretch[<-]: layer$layout()$(row,col)[Set]Stretch()
q(h,v)Spacing<-: layer$layout()$setHorizontal(Vertical)Spacing()
qbackgroundBrush<-: scene$backgroundBrush <- brush
qgraphicsScene: Qt$QGraphicsScene()
qclearSelection: layer$clearSelection()
qzValue<-: layer$setZValue()
qprimitives: layer$primitives()
qminimumSize<-: layer$setMinimumSize()
qcacheMode<-: layer$setCacheMode()
qclip<-: layer$setClip()
qfocus<-: layer$setFocus()
qlimits<-: layer$setLimits
qoverlayScene: layer$overlayScene()

Think of anything else?
