Week 10: Supporting hierarchical animations

What did you do this week?

• Implemented hierarchical order support for animations using matrices in this PR.

• Improved the API of a PartialActor by adding some methods to control the scales, positions and colors.

• Added a new example of using the new hierarchical feature to animate an arm robot.

• Improved vector_text a little by adding options to control its direction.

What is coming up next week?

• Finish the hierarchical order animation support PR.
• Explain tutorials in more detail. See this issue.
• Fix issues discovered by Serge in this review.
• Fix lightColor0 being hard-set to (1, 1, 1). Instead, find a way to get this property the same way other polygon-based actor gets it.
• Try to get PRs and issues mentioned above merged, closed or ready for a final review.

Did you get stuck anywhere?
