=head1 NAME
SDL::Rect - raw object for storing rectangular coordinates
=head1 SYNOPSIS
my $rect = SDL::Rect->new( -height => 4, -width => 40 );
$rect->x(12); # same as $rect->left(12)
$rect->y(9); # same as $rect->top(9)
=head1 DESCRIPTION
C<SDL::Rect::new> creates a SDL_Rect structure which is
used for specifying regions of pixels for filling, blitting, and updating.
These objects make it easy to cut and backfill.
By default, x, y, height and width are all set to 0.
=head2 METHODS
The four fields of a rectangle can be set simply
by passing a value to the applicable method. These are:
=head3 x
=head3 left
sets and fetches the x (lefmost) position of the rectangle.
=head3 y
=head3 top
sets and fetches the y (topmost) position.
=head3 w
=head3 width
sets and fetches the width of the rectangle (in pixels).
=head3 h
=head3 height
sets and fetches the height of the rectangle (in pixels).
