>/**
> * This test creates a {@link Texture} from {@link TextureData} of various pixel formats
> * and pixel types with auto generate mipmaps set to {@code true}.
> * 
> * Bug Reference: https://jogamp.org/bugzilla/show_bug.cgi?id=365
> * 
> * The bug pertains to mipmap generation from a Texture and exists in {@link ScaleInternal} 
> * where a {@link java.nio.BufferUnderflowException} is thrown.
> * 
> * <ul>This suite of test cases test:
> * <li>{@link ScaleInternal#scale_internal_ubyte(int, int, int, ByteBuffer, int, int, ByteBuffer, int, int, int)}</li>
> * <li>{@link ScaleInternal#scale_internal_byte(int, int, int, ByteBuffer, int, int, ByteBuffer, int, int, int)}</li>
> * <li>{@link ScaleInternal#scale_internal_ushort(int, int, int, ByteBuffer, int, int, java.nio.ShortBuffer, int, int, int, boolean)}</li>
