People who aren't debugging graphics code don't need this on every startup. It gets in the way of seeing interesting things like warnings.

Agreed, this should be hidden behind MOZ_GL_DEBUG.

Disable debug output unless MOZ_GL_DEBUG is defined

A stab at fixing this, my first patch.

Disable debug output unless MOZ_GL_DEBUG is defined

Review of attachment 629200 [details] [diff] [review]:

Don't re-read the env var everytime. We already read it, into a |mDebugMode| bitfield, so just check for mDebugMode != 0. If the env var hasn't been read yet when you need it, try shuffling things around.

Disable debug output unless MOZ_GL_DEBUG is defined

Changed per review comment, using sDebugMode.
Moved the sDebugMode mask code‐block further up in the InitWithPrefix function so it is usable.

Review of attachment 629241 [details] [diff] [review]:

Just a couple of nits.

Also, I'm scared that this is playing with the value of |once| which could be tricky in the future. But this is OK as this whole function is a kludge and needs to be refactored completely.

No spaces around the condition inside of the (), and !=0 is useless, so I would write: if (sDebugMode).

I still see the spew on Try:

Maybe the conditional is backwards?

Yeah gosh, thought I’d tested that. New patch coming.

Disable most WEBGL debug output unless env vars set.

Suppresses WebGL init, context messages and outstanding buffers.

Review of attachment 630636 [details] [diff] [review]:

I think that's all of them, though I didn't actually check. But the ones you touch on here are done right.

Eventually, we'd like to drop the #ifdef DEBUG tags around things, since DebugMode() should get inlined to |false|, which should optimized out. However, we haven't check this, so are erring on the side of caution and leaving the #ifdefs for now.

Is this good to push, or should we wait for bjacob to r+ the new patch as well?

Bug 762265 effectively reverted this change without discussion.  I am unhappy about that.

Ouch, yeah, bug collision. This was not at all the intent of bug 762265.

Revert some changes from Bug 762265

No worries, this should undo the change in Bug 762265.
Could you put this through a try please, as I cannot test output from EGL here.

Quiet GFX spew except on the first run in DebugMode()

This ties in the above changes, does a tiny bit of cleanup, and tries to make the logic less convoluted.
