Robin Dunn f52e0cf489 Changed name to wxFIXED_MINSIZE since that is more descriptive of what
it does.  The size can still be changed by the sizer, but it won't
query the minsize if this flag is set.

overview = """\
The <b>wx.MimeTypesManager</b> class allows the application to retrieve the
information about all known MIME types from a system-specific location and the
filename extensions to the MIME types and vice versa. After initialization the
methods <b>GetFileTypeFromMimeType()</b> and <b>GetFileTypeFromExtension()</b>
may be called: they will return a <b>wx.FileType</b> object which may be further
queried for file description, icon and other attributes.
A global instance of <b>wx.MimeTypesManager</b> is always available as
<b>wx.TheMimeTypesManager</b>. It is recommended to use this instance instead
of creating your own because gathering MIME information may take quite a long
on Unix systems.
This demo shows how to use wx.TheMimeTypesManager to list all known MIME types
and retrieve that information as a wx.FileType from either an extension or
MIME type.
For further information please consult the wxWindows documentation for
<b>wx.MimeTypesManager</b> and <b>wx.FileType</b>.
