Fix for Unity Demo as Web Cam Texture is 16x16 and The Demo Does Not Work

[chris-o3h]

The problem is that the web cam texture starts up with a resolution of 16x16 and the example code does not wait until the resolution is actually set. So the reader is looking at a tiny 16x16 portion of the data and will never "see" the image appropriately.

A quick fix to modify the demo:

    void Update()
    {
        if (camTexture.width <= 16) return;

        W = camTexture.width;
        H = camTexture.height;
 // ... and then the rest

The actual version of the method "Update" is the following:

    void Update()
    {
        if (c == null)
        {
            c = camTexture.GetPixels32();
        }

        // encode the last found
        var textForEncoding = LastResult;
        if (shouldEncodeNow &&
            textForEncoding != null)
        {
            var color32 = Encode(textForEncoding, encoded.width, encoded.height);
            encoded.SetPixels32(color32);
            encoded.Apply();
            shouldEncodeNow = false;
        }
    }

Perhaps it should be changed to this one here? What do you think?

    void Update()
    {
        if (c == null)
        {
            c = camTexture.GetPixels32();
            W = camTexture.width;
            H = camTexture.height;
        }
        /// ... and the rest here like above
    }
