\brief
Constructor for Pixmap type fonts.
\param font_name
The name that the font will use within the CEGUI system.
\param imageset_filename
The filename of an imageset to load that will be used as the source for
glyph images for this font. If \a resource_group is the special value
of "*", this parameter may instead refer to the name of an already
loaded Imagset.
\param resource_group
The resource group identifier to use when loading the imageset file
specified by \a imageset_filename. If this group is set to the special
value of "*", then \a imageset_filename instead will refer to the name
of an existing Imageset.
\param auto_scaled
Specifies whether the font imagery should be automatically scaled to
maintain the same physical size (which is calculated by using the
native resolution setting).
\param native_horz_res
The horizontal native resolution value. This is only significant when
auto scaling is enabled.
\param native_vert_res
The vertical native resolution value. This is only significant when
auto scaling is enabled.
