size
A list specifying the dimensions of the texture.
viz.TEX_1D only requires a single dimension, [width].
viz.TEX_2D, viz.TEX_RECT, and viz.TEX_CUBE require 2 dimensions, [width,height].
viz.TEX_3D requires 3 dimensions, [width,height,depth].
This command will create a blank texture that can be used for manual modifications. Unlike
<viz>.addRenderTexture, this command will allocate image memory so the
<texture>.getImageData command will return valid data. The pixel values are all initialized to 0 (black).
