+Description:
+ File to set up test cases for the Graphite regression test program.
+
+How to add a test:
+ 1. Add the name of your test method to the class declaration in TestCase.h.
+ 2. Increment the g_numberOfTests constant in this file.
+ 3. Add a call to your test method in the SetupTests method in this file.
+ 4. Copy one of the existing test methods such as SetupSimpleTest and change the name
+ and data.
+
+Things that still need testing:
+ Ligatures (there is one small test of this)
+ Justification
+ Fake italic
