This data structure is the standard form for an error record used for reporting
errors to application code.

Used in:

PK_ERROR_ask_last
PK_ERROR_frustrum_t
PK_ERROR_raise
PK_THREAD_ask_last_error

This is used to pass information to the application supplied error handler
and from PK_ERROR_ask_last and PK_THREAD_ask_last_error.

If there have been no errors, or the last error has been cleared, 'function'
will be the name of the PK function that asked for the last error, 'code' will
be PK_ERROR_no_errors and 'severity' will be PK_ERROR_none.
