Similar to above, but using a MoonWorks vertex buffer and custom vertex structs.
**StoreLoad**
Draws a triangle to the screen in one render pass, stores the attachment, and then loads the attachment again. Tests that load/store operations work as expected.

Draws a textured quad to the screen. Tests texture binding, index buffers, and sampler states.

Displays a triangle whose colors are driven by sampling a texture in the vertex shader.
**RenderTexture2D**
Clears and draws 4 render textures to the screen. Tests binding and sampling 2D render textures.
**RenderTexture3D**
Fades through 2D slices of a 3D render texture. Tests binding and sampling 3D render textures.
