Add usage guideline comments for custom GL context priority.

Add usage guideline comments for custom GL context priority.

Due to conflicts with the GVR library, we had to stop using this for the VR
browser mode. I think this attribute is still useful for the future, but we
should use it to reduce priority of possibly-slow user GL code instead of using
"high" priority ourselves.
