* Error.cpp

*
|
|
* Error reporting for 3D renderer. There are some situations in which it is
|
|
* appropriate to inform the user of an error during rendering. However, these
|
|
* will frequently lead to an avalanche of error messages. Therefore, error
|
|
* messages are managed by this interface, ensuring that they are displayed not
|
|
* more than once per frame.
|
|
*
|
|
* Error functions can always be counted on to return FAIL, like ErrorLog().
