+ Returns the size of bitmap that the toolbar expects to have.
+
+ The default bitmap size is platform-dependent: for example, it is 16*15
+ for MSW and 24*24 for GTK. This size does @em not necessarily indicate
+ the best size to use for the toolbars on the given platform, for this
+ you should use @c wxArtProvider::GetNativeSizeHint(wxART_TOOLBAR) but
+ in any case, as the bitmap size is deduced automatically from the size
+ of the bitmaps associated with the tools added to the toolbar, it is
+ usually unnecessary to call SetToolBitmapSize() explicitly.
