* Error macros.
* WARNING: These macros work in the opposite way to assert().
*
* Unlike exceptions and asserts, these macros try to maintain consistency and stability.
* In most cases, bugs and/or invalid data are not fatal. They should never allow a perfectly
* running application to fail or crash.
* Always try to return processable data, so the engine can keep running well.
* Use the _MSG versions to print a meaningful message to help with debugging.
*
* The `((void)0)` no-op statement is used as a trick to force us to put a semicolon after
* those macros, making them look like proper statements.
* The if wrappers are used to ensure that the macro replacement does not trigger unexpected
* issues when expanded e.g. after an `if (cond) ERR_FAIL();` without braces.
