  27     wxCocoa's implementation of wxFont is very incomplete.  In particular,
  28     a lot of work needs to be done on wxNativeFontInfo which is currently
  29     using the totally generic implementation.
  30
  31     See the documentation in src/cocoa/font.mm for more implementatoin details.

 103         The intention here I suppose is to allow one to create a wxFont without yet
 104         creating the underlying native object.  There's no point not to create the
 105         NSFont immediately in wxCocoa so this is useless.
 106         This method came from the stub code copied in the early days of wxCocoa.
 107         FIXME(1): Remove this in trunk.  FIXME(2): Is it really a good idea for this to
 108         be part of the public API for wxGDIObject?
