Laszlo Agocs 870a3011ed rhi: Add a displacement / tessellation manual test
There is something odd when running on Metal: note how the uv
is vec3 instead of vec2, in order to make the vertex-tesc-tese
data to look like this:

struct main0_out
{
    float3 out_uv;
    float3 out_normal;
    float4 gl_Position;
};

if out_uv was float2 we'd get some strange rendering results,
perhaps due to something related to alignment. But have no means
to investigate this further.
