Assuming the handlers have been written correctly, you should now be able to load and save PNG files
and XPM files using the usual wxBitmap API.

{\bf Note:} bitmap handlers are not implemented on all platforms. Currently, the above is only necessary on
Windows, to save the extra overhead of formats that may not be necessary (if you don't use them, they
are not linked into the executable). Unix platforms have PNG and XPM capability built-in (where supported).

Also, just because a handler (such as a PNG handler) is not present does not mean that
wxBitmap does not support that file format. If wxBitmap fails to find a suitable handler,
the file-loading capabilities of wxImage are used instead.
