+ Note that on wxGTK wxAnimation is capable of loading the formats supported
+ by the internally-used @c gdk-pixbuf library (typically this means only
+ @c wxANIMATION_TYPE_GIF).
+ On other platforms wxAnimation is always capable of loading both GIF and ANI
+ formats (i.e. both @c wxANIMATION_TYPE_GIF and @c wxANIMATION_TYPE_ANI).
