+// ### Qt 5: eliminate this file
+
+/*
+    This is evil. MSVC doesn't let us remove private symbols, nor change their
+    visibility; yet there are some symbols we really needed to make public, e.g.,
+    ~QColorDialog(), and then there were some totally needless symbols in our
+    header files, e.g., setSelectedAlpha(). So we define a new version of
+    QColorDialog & Co. with only the private symbols that we removed from the
+    public header files. The friends are there only to prevent potential compiler
+    warnings.
+
+    It would have been nicer to export the missing symbols as mangled "C" symbols
+    instead but unfortunately MSVC uses out-of-reach characters like @ and . in
+    their mangled C++ symbols.
