Avoid flipping in AWTTextureIO

If I create a textureData through

TextureIO.newTextureData(GLProfile glp, URL url, boolean bln, String string)

everything fine

If I do through

AWTTextureIO.newTextureData(GLProfile glp, BufferedImage bi, boolean bln)

flips automatically the image

        mustFlipVertically = true;

second line in AWTTextureData.createFromImage


            test = new int[1];
            gl3.glGenTextures(1, test, 0);
            gl3.glBindTexture(GL3.GL_TEXTURE_2D, test[0]);
            {
                System.out.println("textureData.getMustFlipVertically() " + textureData.getMustFlipVertically());
                textureData.setMustFlipVertically(false);
                System.out.println("textureData.getMustFlipVertically() " + textureData.getMustFlipVertically());
                gl3.glTexImage2D(GL3.GL_TEXTURE_2D, 0, textureData.getInternalFormat(), textureData.getWidth(),
                        textureData.getHeight(), textureData.getBorder(), textureData.getPixelFormat(),
                        textureData.getPixelType(), textureData.getBuffer());
                gl3.glTexParameteri(GL3.GL_TEXTURE_2D, GL3.GL_TEXTURE_BASE_LEVEL, 0);
                gl3.glTexParameteri(GL3.GL_TEXTURE_2D, GL3.GL_TEXTURE_MAX_LEVEL, 0);
            }
            gl3.glBindTexture(GL3.GL_TEXTURE_2D, 0);

this print

true
false

but the texture is still rendered flipped

Hi

I had the same kind of trouble when I ported the alpha version of my game to JOGL 2. mustFlipVertically is an hint used by the Texture class. If you use TextureData without Texture, you have to look at the hint to decide whether flipping the texture coordinates or the data. I flip the data in JogAmp's Ardor3D Continuation, feel free to look at my code.

I solved using the utility

        ImageUtil.flipImageVertically(bufferedImage);

It's a good method but it is slower than what I do in JogAmp's Ardor3D Continuation. I assume it's enough for you.

I am using it for icons 100x25 pixels, I guess it is ok
