Log shader compile errors with Warning level (#2617)
* Log shader compile errors with Warning level

These are infrequent enough that I think it's worth dumping any errors into the log. They also keep causing graphical glitches, and the only indication that anything went wrong is a debug log that is never enabled.

* Add maximum length for shader log
