/ Ambient Lighting Shader
/
/ OUTLINE:
/ This shader draws the object in a solid color given by the materials ambient color.
/
/ IMPLEMENTATION:
/ The vertex shader transforms the vertex to clip space. The pixel shader multiplies the
/ ambient color by the ambient intensity and returns that as the final pixel color.
/
/ NOTES:
