Outdated comment.
Formatting and nitpicking.
Remove outdated build script.
Fix vertexspecification.d:
  - shader #directives lines must end with \n
  - Fix #version to make it work on NVIDIA
[examples] Allman formatting. Removing comments talking about "ownership" since it might lead people to think a VertexSpecification will release the associated Buffer but this is false, such Buffer must outlive their VertexSpecification.
Add GLBuffer convenience method.
Rename getVertexSize() to vertexSize().
A bit of example cleanup: use merged shaders, move things around and formatting.
One more convenience method and example simplifying.
