Fix custommaterial example with OpenGL

The member names in the "uniform block" (which is in practice
mapped to a struct uniform with GLSL) must match between the
vertex and fragment shaders, even if the member is not used in
one of the shaders. This is because OpenGL/GLSL's interface
matching rules, which would cause the shader program fail to
link due to a mismatch in the structs in the two shaders.
