Support CPU side culling of scenegraph nodes

    XMLWordPrintable

Details

    Description

      For some embedded hardware it can be beneficial to do CPU side culling of nodes that are outside of the viewport or clip region.

      One discussed approach is to introduce an internal flag itemCullsChildren that could be used by certain items such as Flickable and PathView where this problem often occurs. The actual culling could be done in QQuickWindow::updateDirtyNodes.
