// this is a whitespace and other invisible token torture test for the ANTLR-based
// preprocessor.  edit pde.properties and set "editor.save_build_files" to true.
// then, build this in processing.  next, use
//
// diff -u --strip-trailing-cr \ 
//   work/sketchbook/default/whitespace_test/whitespace_test.pde \ 
//   work/lib/build/MyDemo.java
//
// to compare the files before and after preprocessing.  There should not be 
// any differences.
