From 8e9771d15c3e328fb5183f78f37501f9f2646c09 Mon Sep 17 00:00:00 2001
From: Denis Kasak
Date: Fri, 3 Jul 2009 16:41:11 +0000
Subject: Added bool parameter markDirty to Sprite::draw() and Text::draw() to
 specify whether to mark a dirty rect for a particular draw (also added such
 support to the Font class since it's needed by Text). Made spacing parameters
 for Text instances mandatory.
