#===Options
#
# * <tt>:tag or :with</tt> - Use predefined tag
# * <tt>:color</tt> - Override color of the tag
# * <tt>:align</tt> - Align of the text
#===Examples
# The vertical line is the current point. For align by point
# doc.moveto :x => 3, :y => 4
# doc.show "Foo Bar Baz", :align => :show_left #default
# link:images/show01.png
#
# doc.moveto :x => 3, :y => 4
# doc.show "Foo Bar Baz", :align => :show_center
# link:images/show02.png
#
# doc.moveto :x => 3, :y => 4
# doc.show "Foo Bar Baz", :align => :show_right
# link:images/show03.png
#
# For the the current row it's not necessary positioned using moveto. Like below
# doc.show "Foo Bar Baz", :align => :show_right
# Now justification in page
#
# doc.show "Foo Bar Baz", :align => :page_left
#
# link:images/show04.png

# doc.show "Foo Bar Baz", :align => :page_center
#

#
# doc.show "Foo Bar Baz", :with => :my_italic, :align => :page_center, :color => :red
#
# link:images/show07.png
#
# Many tags per row
# doc=Document.new
# doc.define_tags do
# tag :font1, :name => 'Helvetica', :size => 10, :color => '#F34811'
# tag :font2, :name => 'Times', :size => 14, :color => '#A4297A'
# tag :font3, :name => 'TimesBold', :size => 18, :color => '#AA3903'
