Has anyone else noticed that GLUtils.texImage2D seems to want the image to 
be upside down?

GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0);

One way to see this is to look at Cosmin Banu's NeHe code here:


http://code.google.com/p/nehe-android/source/browse/trunk/NeHe06/src/ro/brite/android/nehe06/Utils.java

He has this in there:

      private static Matrix yFlipMatrix;
        
        static
        {
                yFlipMatrix = new Matrix();
                yFlipMatrix.postScale(1, -1); // flip Y axis
        }

And this:

return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), 
bitmap.getHeight(), yFlipMatrix, false);


I have independently noticed this, and it caused a lot of frustration.

Any ideas how to best solve this?  Obviously, if we "just fix it", it will 
break a lot of old code that relies on its currently incorrect behavior.
