Added image scene to render an image in a scene. There is also now
a testing image that is an uber meme. Currently the problem is
that the spritebatch cannot use the offsetof macro because it is a
templated class. Possible solutions to this are changing it to be
specifyable or implemented per vertex type as the other batches
have been.
MyBuiltinTexturedScene (number 7) displays a cube that loads its
faces from a hard-coded texture. Mipmaping is supported. Just use
the XXX_MIPMAP_XXX Min/Mag filters to use it. TODO next is
combining lighting and textures and then up after that is shadows.
I may just do lighting and shadows before lighting, shadows, and
textures.
Now, LitScene allows for simple lighting. (Shadows still to come).
Ambient, specular, and diffuse lighting available and each mesh's
vertex can define a material that defines its reflectivity. An
example scene was added to the MyApplication as the scene for the
6 button.
Need to re-make the builtin version. The problem, again, was caused
by vtables. Need to find a way to make interfaces without virtual
methods to remove the need for vtables. Found a good stackoverflow
article on this.

The Positioned, Normaled, Textured, etc. Interfaces should be
re-made using this format.
Builtin general structure created. Added a builtin::BasicScene
class for quick general testing of the engine on different systems.
The builtin::BasicScene class greatly reduces the amount of code
needed to be handled by the developer by offering a pre-made way
to handle it. It even includes pre-made shaders!
Starting the setup for builtin types for rendering. This will allow
the engine to be easier to use for beginners while still offering
great modularity and functionality. The builtin namespace is
intended to simplify mesh loading and rendering. It should
eventually offer pre-made shaders to simplify the rendering of the
builtin types. Possibly in the future, it could have partially
setup scenes/application to simplify scene/application building
