+        [Qt] Fix compilation with win32-icc
+
+        The Intel compiler does not support the __has_trivial_constructor type
+        trait.  The Intel Compiler can report itself as _MSC_VER >= 1400. The
+        reason for that is that the Intel Compiler depends on the Microsoft
+        Platform SDK, and in order to try to be "fully" MS compatible it will
+        "pretend" to be the same MS compiler as was shipped with the MS PSDK.
+        (Thus, compiling with win32-icc with VC8 SDK will make the source code
+        "think" the compiler at hand supports this type trait).

     If you need to interpolate other variant types, including custom
     types, you have to implement interpolation for these yourself.
-    You do this by reimplementing interpolated(), which returns
+    To do this, you can register an interpolator function for a given
+    type. This function takes 3 parameters: the start value, the end value
+    and the current progress.
+
+    Example:
+    \code
+        QVariant myColorInterpolator(const QColor &start, const QColor &end, qreal progress)
+        {
+            ...
+            return QColor(...);
+        }
+        ...
+        qRegisterAnimationInterpolator<QColor>(myColorInterpolator);
+    \endcode
+
+    Another option is to reimplement interpolated(), which returns
     interpolation values for the value being interpolated.
