True. Rotation is quite easy and fast with OpenGL. But even with using
OpenGL you have to implement LUT transformations and image manipulation
functions. You also have to implement lists of graphical objects you
want to manipulate. OpenGL is just another path to the graphics hw.

My intention is to create a viewer that will also run on non-overpowered
hardware. But you're right using OpenGL as optional display path is
considerable.

As said above. The image manipulation methods would be the same.
