=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.
