`PrimitiveType` determines how a stream of vertex information will be interpreted as shapes by the pipeline. There are 5 types of primitives that MoonWorks supports.
`PointList` will interpret the data as a list of points.
`LineList` will interpret the data as a list of lines.
`LineStrip` will interpet the data as a strip of lines.
`TriangleList` will interpret the data as a list of triangles.
`TriangleStrip` will interpret the data as a strip of triangles.
The primitive type you will use the most by far is `TriangleList` - the vast majority of 3D model exporters will give you vertex data in the form of a list of triangles. The others are mostly niche cases.
