Avoid measuring the length of strings repeatedly by passing their length along with their data with `StringRefNull`. Null termination seems to be necessary still for passing the shader sources to OpenGL. Though I doubt this is a bottleneck, it's still nice to avoid overhead from string operations and this helps move in that direction.
