The minimumRenderSize is a qreal value that is used as a lower bound to determine what items are visible when a scene is rendered. If an item's view-transformed width or height are less than minimumRenderSize then this item is considered to insignificantly affect the final result and is not drawn. If the item clips its children to its shape they are automatically not drawn. This greatly reduces the drawing overhead for scenes with many items rendered in a zoomed out view. [ChangeLog][QtWidgets][QGraphicsScene] Added the minimumRenderSize property which can be used to speed up rendering by not painting items, smaller than a give size.
