Import r67258 of the wxWidgets trunk, which I expect will before

long become wxWidgets 2.9.2, which in turn is expected to be the
last 2.9 release before the 3.0 stable release.

Since the full wxWidgets distribution is rather large, I have
imported only the parts that we use, on a subdirectory basis:

+ * NB: I don't see how this class may possibly be useful to the application
+ *     program (as the settings are lost on program termination), but it is
+ *     handy to have it inside wxWidgets. So for now let's say that this class
+ *     is private and should only be used by wxWidgets itself - this might
