Description
Hi,
I needed an indexed accessor to the Vector3 components, so I extended the code. Below is the SVN patch.
I'm new to OpenTK. Is there a better way to submit changes? I didn't need it right now, but for completeness' sake I will port this extension to the other vector classes if this change is accepted.
