How to be able to select full rotations (0,25,50,75) with one slider?

UPDATED SINCE FIRST POSTED

Here I have found a possible way to be able to have the rotation only at the 4 fixed full rotated version AND that does not use the Rotate component so it is still compatible with the FF Seamless option because the Rotate is a non-seamless component

I needed to be able to use the rotation component equivalent (with seamless) but that the slider only has 4 points that it would give a fixed value that would give a full rotated version of the source content, I mean as follows

0, 0.25, 0.50 or 0.75 Using Value control
0, 25, 50, or 75 Using Slider
0, 90, 180 or 270 Using Angle Control

So I searched in the forum and found this thread about rotation in degrees and found that CFandM have an awesome and clever solution in the 8th post that is Rotate Zoom 2 by CFandM but this includes a zoom option

So I have modified it and removed the zoom part and leave only the rotation in fixed degrees part and fixed the wrong order of rotation

Want to give a huge thanks to CFandM for making this possible
