void SciFigs::LayerPainterRequest::setDepth ( int depth )

Depth is relative to the final display. It is not the layer index to start with. A depth of 0 is for starting from the uppermost layer. A depth of -1, means do nothing.

Can be called only outside a painting thread. Set the depth of painting. It is automatically adjusted to available layer images (setLayerImage() must be called before).
