=head1 NAME

Gtk2::Pango - constants for use with Pango

=head1 SYNOPSIS

  use Gtk2; # gets the actual Pango objects and methods

  use Gtk2::Pango; # load extra constants

=head1 DESCRIPTION

To use Pango effectively, you need a few extra constants that are not
supplied in normal ways by the type system or by other means.

This module exports all of those extra constants when you load it.
They use the fully-prefixed names from the C documentation.

=head1 EXPORT

PangoWeight is indeed defined as an enumerated type whose values can be
used as nickname strings in the perl bindings, but in several places 
where a weight is needed, a gint is requested instead.  This is because
PangoWeight is actually just a set of predefined values for an integer-valued
property.  The PANGO_WEIGHT_* constants give you the predefined values:

	PANGO_WEIGHT_ULTRALIGHT
	PANGO_WEIGHT_LIGHT
	PANGO_WEIGHT_NORMAL
	PANGO_WEIGHT_BOLD
	PANGO_WEIGHT_ULTRABOLD
	PANGO_WEIGHT_HEAVY

These are #defined in the C source, and thus are not available anywhere
except here:

	PANGO_SCALE_XX_SMALL
	PANGO_SCALE_X_SMALL
	PANGO_SCALE_SMALL
	PANGO_SCALE_MEDIUM
	PANGO_SCALE_LARGE
	PANGO_SCALE_X_LARGE
	PANGO_SCALE_XX_LARGE

PANGO_SCALE is needed to convert between Pango units and pixels.
It is also available as Gtk2::Pango->scale.

	PANGO_SCALE

=head1 BUGS

This module shouldn't exist, but some parts of the API just aren't clean.

This stuff is hardcoded directly from the headers of pango 1.2.1.
