[Bug?] jit.gl.sketch GLU tessellation and glutessmatrix

LLT's icon

Hi, I did several tests with the GLU tessellation and glutessmatrix in jit.gl.sketch and things did not go as I thought. With a matrix glutessmatrix it works. But with @matrixoutput in jit.gl.gridshape it does not work and it does not work with jit.gen.

In jit.gen if I change snorm to norm can be seen in the matrix appear sometimes.

I probably missed something on the side triangles :)
