[jitter] Re: I need help, I can not find where is the problem with my patch (jit.gl.videoplane, jit.gl.slab)

Ok,
You don't send a videoplane to a slab.  You have some major
misconceptions about how things work in OpenGL.  Please read the
following _very_ carefully.

1a) Slabs work with textures.  They take textures as input and give
textures as output
1b) Slabs can also work with matrices.  When a matrix is sent to a
slab, internally it is converted to a texture.
2) A videoplane is a plane in space.  It is geometry, not a texture.
It is used to display textures in OpenGL.

HTH,
