    this is that Nokia focuses on OpenGL for desktop hardware accelerated
    rendering.
 
- - When mixing OpenGL and QPainter calls you need to first call syncState()
-   on the paint engine, for example "painter->paintEngine()->syncState()".
-   This is to ensure that the engine flushes any pending drawing and sets up
-   the GL modelview/projection matrices properly.
+ - When mixing OpenGL and QPainter calls you need to surround your custom
+   OpenGL calls with QPainter::beginNativePainting() and
+   QPainter::endNativePainting().
+   This is to ensure that the paint engine flushes any pending drawing and sets
+   up the GL modelview/projection matrices properly before you can issue custom
+   OpenGL calls, and to let the paint engine synchronize to the painter state
+   before resuming regular QPainter based drawing.
 
  - Graphics View has undergone heavy optimization work, and as a result of
    this work, the following behavior changes were introduced.

           the widget is transformed resolution independently, allowing the

           of resolution independence depends on the style.)

+    \section1 Performance
+
+      \section2 Floating Point Instructions
+
+        In order to accurately and quickly apply transformations and effects to
+        items, Graphics View is built with the assumption that the user's hardware
+        is able to provide reasonable performance for floating point instructions.
+
+        Many workstations and desktop computers are equipped with suitable hardware
+        to accelerate this kind of computation, but some embedded devices may only
+        provide libraries to handle mathematical operations or emulate floating
+        point instructions in software.
+
+        As a result, certain kinds of effects may be slower than expected on certain
+        devices. It may be possible to compensate for this performance hit by making
+        optimizations in other areas; for example, by using \l{#OpenGL Rendering}{OpenGL}
+        to render a scene. However, any such optimizations may themselves cause a
+        reduction in performance if they also rely on the presence of floating point
+        hardware.
