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.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
