Which is why we any predefined image manipulation should avoid the ARM core and jump straight to the rather powerful GPU. I think it even supports OpenCL, so there should be software out there that could work with it.

The GPU on the Pi can't/won't support OpenCL. That doesn't stop one from writing a GPGPU program in GLSL.
