Typically text expects a string. But Rails views have this interesting concept that they implicitly call `to_s` on all the variables before rendering. So, passing an integer to text fails:
pdf.text 10 #=> fails because 10 is not a string pdf.text 10.to_s #=> works
To circumvent this situation, we call to_s on value, and delegate action to actual Prawn::Document.
Calls superclass method
# File lib/prawn-rails/document.rb, line 29 def text(value, options = {}) super(value.to_s, options) end
