=head1 NAME
SDL::Tool::Graphic
=head1 DESCRIPTION
L<SDL::Tool::Graphic> is a module for zooming and rotating L<SDL::Surface> objects.
=head1 METHODS
=head2 zoom ( surface, xzoom, yzoom, smooth )
C<SDL::Tool::Graphic::zoom> scales a L<SDL::Surface> along the two axis independently,
and returns a new L<SDL::Surface> object.
=head2 rotoZoom ( surface, angle, zoom, smooth )
C<SDL::Tool::Graphic::rotoZoom> rotates and fixed axis zooms a L<SDL::Surface>
and returns a new L<SDL::Surface> object.
