=head1 NAME
SDL::Rect - a SDL perl extension
=head1 SYNOPSIS
$rect = new SDL::Rect ( -height => 4, -width => 40 );
=head1 DESCRIPTION
C<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, h, w are 0.
=head2 METHODS
The four fields of a rectangle can be set simply
by passing a value to the applicable method. These are:
=over 4
=item *
C<SDL::Rect::x> sets and fetches the x position.
=item *
C<SDL::Rect::y> sets and fetches the y position.
=item *
C<SDL::Rect::width> sets and fetched the width.
=item *
C<SDL::Rect::height> sets and fetched the height.
