All writes to valid_buffer_range are protected by a mutex. Onl=
y the reads are
not.

I've got no idea what to do with invalidate_buffer. If we added mutexes

I think that calling BufferData in one thread and using the buffer for
rendering in some other thread is a race condition in the application and
should be fixed in the app.
