Thanks for the tips markdavid,

I made the changes. I am in the learning curve with lua. I am  
building some shapes with lua so I can have multiple shapes drawn  
with instances of jit.gl.mesh. That part is working. Although I am  
still trying to figure out drawraw in some respects because Joshua  
said it would be faster.

Now I am trying to texture those shapes and thought I would create as  
many instances of jit.qt.movie to load onto my instances of  
jit.gl.texture. But I will not only be working with short movies.  
Some might be longer. So because of this limitation I will probably  
either go with the example I found in the archive of uploading frames  
of the videos to textures outside of lua and then binding them with  
the example of quads which wes posted a while ago or copy the output  
of the jit.qt.movie objects outside of jit.gl.lua to instances of  
jit.gl.matrix that are copied to instances of jit.gl.texture within  
lua. Then jit.gl.lua would just be for the opengl stuff and possibly  
uploading the textures.

Beyond that I am posting what I am figuring out using matrices in  
jit.gl.lua because it might be useful to others using lua.

Sorry to tear up the bandwidth with this.
