=head1 NAME

SDL::Rect - a SDL perl extension

=head1 SYNOPSIS

  $rect = new SDL::Rect ( -height => 4, -width => 40 );

=head1 DESCRIPTION


	SDL::Rect->new(...); creates a SDL_Rect structure which is
used for specifying regions for filling, blitting, and updating.
These objects make it easy to cut and backfill.

By default, x, y = 0, and h, w default to 0. (the default
scratch sizes);

=head2 Rect fields

	The four fields of a rectangle can be set simply
by passing a value to the applicable method.  These are:

	$rect->x(4);		# sets x to 4
	$rect->y();		# reads y
	$rect->width(49);	# sets width to 49
	$rect->height();	# reads height
