/* These macros can be used when initializing cached ids stored in the QtCachedIDs structure.
   They should be called from static initializes of classes to get any IDs they use.
   In debug mode, they will check the ID exists and return if not (causing an exception to be thrown).
   In non-debug mode they are optimised for space and performance to assume the ID exists. This
   is because they are probably romized with the classes and once they work it is not necessary
   to check every time that they exist. */
