I don't understand why you're trying to copy the texture from a Bitmap
into an IntBuffer before setting it. Why not use GLUtils.texImage2D to
load the Bitmap directly?

Pretty much the rule with 3D stuff is that you always use power-of-2

If you just want to get some animation running quickly, don't worry
