Creates a mesh whose vertices describe a quad consisting of two triangles,
with the specified width and height. If the vertex descriptor allows for
normals and/or texture coordinates, they are added.

@param ctx         GVRContext to use for creating mesh.
@param vertexDesc  String describing vertex format of {@link GVRVertexBuffer}
@param width       the quad's width
@param height      the quad's height
@return A 2D, rectangular mesh with four vertices and two triangles
