+/**

+ * This test creates a {@link Texture} from {@link TextureData} of various pixel formats

+ * and pixel types with auto generate mipmaps set to {@code true}.

+ * <br></br>

+ * Bug Reference: https://jogamp.org/bugzilla/show_bug.cgi?id=365

+ * <br></br>

+ * The bug pertains to mipmap generation from a Texture and exists in {@link ScaleInternal} 

+ * where a {@link java.nio.BufferUnderflowException} is thrown.

+ * <br></br>

+ * <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>
