-    QGraphicsItem supports affine transformations in addition to its base
-    position, pos(). To change the item's transformation, you can pass
-    a transformation matrix to setTransform()
-
-    Item transformations accumulate from parent to child, so if both a
-    parent and child item are rotated 90 degrees, the child's total
-    transformation will be 180 degrees.  Similarly, if the item's
-    parent is scaled to 2x its original size, its children will also
-    be twice as large. An item's transformation does not affect its
-    own local geometry; all geometry functions (e.g., contains(),
-    update(), and all the mapping functions) still operate in local
-    coordinates. For convenience, QGraphicsItem provides the functions

+    QGraphicsItem supports projective transformations in addition to its base
+    position, pos(). There are several ways to change an item's transformation.
+    For simple transformations, you can call either of the convenience
+    functions setRotation() or setScale(), or you can pass any transformation

-    Another way to apply transformation to an item is to use the , or
-    set the different transformation properties (transformOrigin,
-    x/y/zRotation, x/yScale, horizontal/verticalShear).  Those
-    properties come in addition to the base transformation
+    Certain transformation operations produce a different outcome depending on
+    the order in which they are applied. For example, if you scale an
+    transform, and then rotate it, you may get a different result than if the
+    transform was rotated first. However, the order you set the transformation
+    properties on QGraphicsItem does not affect the resulting transformation;
+    QGraphicsItem always applies the properties in a fixed, defined order:
 
-    The order you set the transformation properties does not affect
-    the resulting transformation The resulting transformation is
-    always computed in the following order
-
-    \code
-    [Origin] [Base] [RotateX] [RotateY] [RotateZ] [Shear] [Scale] [-Origin]

+/*!
+    \class QGraphicsTransform
+    \brief The QGraphicsTransform class is an abstract base class for building
+    advanced transformations on QGraphicsItems.
+    \since 4.6
+
+    As an alternative to QGraphicsItem::transform, QGraphicsTransform lets you
+    create and control advanced transformations that can be configured
+    independently using specialized properties.
+
+    QGraphicsItem allows you to assign any number of QGraphicsTransform
+    instances to one QGraphicsItem. Each QGraphicsTransform is applied in
+    order, one at a time, to the QGraphicsItem it's assigned to.
+
+    QGraphicsTransform is particularily useful for animations. Whereas
+    QGraphicsItem::setTransform() lets you assign any transform directly to an
+    item, there is no direct way to interpolate between two different
+    transformations (e.g., when transitioning between two states, each for
+    which the item has a different arbitrary transform assigned). Using
+    QGraphicsTransform you can interpolate the property values of each
+    independent transformation. The resulting operation is then combined into a
+    single transform which is applied to QGraphicsItem.
+
+    If you want to create your own configurable transformation, you can create
+    a subclass of QGraphicsTransform (or any or the existing subclasses), and
+    reimplement the pure virtual applyTo() function, which takes a pointer to a
+    QTransform. Each operation you would like to apply should be exposed as
+    properties (e.g., customTransform->setVerticalShear(2.5)). Inside you
+    reimplementation of applyTo(), you can modify the provided transform
+    respectively.
+
+    QGraphicsTransform can be used together with QGraphicsItem::setTransform(),
+    QGraphicsItem::setRotation(), and QGraphicsItem::setScale().
