At the moment, the image that is obtained from OpenGL is flipped vertically. This is a feature of OpenGL rendering, so I have to fix it manually.
There are two ways to fix it that GLJPanel uses:
Software
This method requires the usual iteration over the image line by line.
In theory, this will consume huge resources.
Hardware
The most preferred way would be to use FBO/GLSL vertical flipping.
It transforms the entire image in the buffer, so the way of reading will not change much.
