  Prevent stack overflow in macro expansion
  
  Add a configurable limit for how many nested MacroExpander objects can
  be created in the preprocessor, so that stack overflow can be
  prevented in case of malicious shaders. By default the limit is set to
  1000. In unit tests the limit is set lower to make the test run
  faster.
  
  Includes refactoring of most of the preprocessor tests so that they
  use utility functions provided by the test class instead of repeating
  the same code for initializing the preprocessor.
