Previously, various error handling functions were defined, but not all of them were even used. The new error handling functions handle the most common cases: - Assertions. These can be handled with `ASSERT()`, which gives the error location for debugging. - Errors we don't know how to handle, like GetNewWindow returning NULL. These can be handled with `EXIT_INTERNAL()`, which gives the error location for debugging. - Out of memory conditions. These can be handled with `ShowMemError()`. - System errors in response to user operations. These can be handled with `ShowError()`.
