=head1 NAME

Image::TextMode::Reader::ANSIMation - Reads ANSI Animation files

=head1 DESCRIPTION

Provides reading capabilities for the ANSIMation format. This module
extends the ANSI reader, and simply creates a new frame for every
C<set_position(0,0)> command executed.

=head1 METHODS

=head2 set_position( [$x, $y] )

We use this method as a clue that we're starting a new frame if $x and $y are
both 1, which is the default.

=head2 next_frame( )

Adds a new frame to the stack.
