replace standard art with their own version. All

+If you need bitmap images (of the same artwork) that should be displayed at different sizes
+you should probably consider overriding \helpref{CreateIconBundle()}{wxartprovidercreateiconbundle}
+and supplying icon bundles that contain different bitmap sizes.
+
There's another way of taking advantage of this class: you can use it in your code and use
platform native icons as provided by \helpref{wxArtProvider::GetBitmap}{wxartprovidergetbitmap} or
\helpref{wxArtProvider::GetIcon}{wxartprovidergeticon} (NB: this is not yet really
possible as of wxWidgets 2.3.3, the set of wxArtProvider bitmaps is too
small).

+Every bitmap and icon bundle are known to wxArtProvider under an unique ID that is used when
