-=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
+# Autoload methods go after __END__, and are processed by the autosplit program.
-=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).
