Shawn Rutledge 48b1af941c Fix QTransform::quadToQuad() to work with QRectF
A typical usage for mapping a 4-point polygon to a rectangle might be

  QTransform transform;
  bool ok = QTransform::quadToQuad(polygon, polygon->boundingRect(),
                                   transform);

It works because the QPolygonF(QRectF) ctor is implicitly called on
the second argument; but that ctor turns it into a 5-point polygon.
So it should be legal for QTransform functions to work with 5-point
closed paths.

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.
