Emulator

What went wrong?
There's no way for the user to tell if shader debugging is enabled other than manually opening the gfx config ini and looking it up. Given that the option has a huge performance impact and that we don't want users to accidently enable it, we should probably put a WARN_LOG in the code to notify users that it's enabled.

What did you expect to happen?
Something to happen that tells the user that shader debugging is enabled.

What steps will reproduce the problem?

1. Enable shader debugging via gfx config ini
2. Desparately look for a way to figure out if shader debugging is enabled without looking at the config ini again.
