/*
 * WHAT THIS TEST DOES
 *
 * This test tests that for all public APIs Cairo behaves correct, consistent
 * and most of all doesn't crash. It does this by calling all APIs that take
 * surfaces or contexts and calling them on specially prepared arguments that
 * should fail when called on this function.
 *
 * ADDING NEW FUNCTIONS
 *
 * You need (for adding the function cairo_surface_foo):
 * 1) A surface_test_func_t named test_cairo_surface_foo that gets passed the
 *    prepared surface and has the job of calling the function and checking
 *    the return value (if one exists) for correctness. The top of this file
 *    contains all these shim functions.
 * 2) Knowledge if the function behaves like a setter or like a getter. A 
 *    setter should set an error status on the surface, a getter does not
 *    modify the function.
 * 3) Knowledge if the function only works for a specific surface type and for
 *    which one.
 * 4) An entry in the tests array using the TEST() macro. It takes as arguments:
 *    - The function name
 *    - TRUE if the function modifies the surface, FALSE otherwise
 *    - the surface type for which the function is valid or -1 if it is valid
 *      for all surface types.
 *
 * FIXING FAILURES
 *
 * The test will dump failures notices into the api-special-cases.log file (when 
 * it doesn't crash). These should be pretty self-explanatory. Usually it is 
 * enough to just add a new check to the function it complained about.
