I've already tested it.
It fixes glMapBufferRange and doesn't fix glBufferSubData.

glMapBufferRange is faster than what we currently use for buffer streaming(glBufferData) but the source isn't set up to use glMapBufferRange with a desktop GL extension. Not sure how much of an improvement there will be to support it yet.
