Changing some values to be relative

I spent a while (more than i expected) changing some strange values that control some settings of a component called cover-flow (this component create and control the images that are displayed in the home screen).
I spent more time figuring out what where each variable and lhe logic behind than acually writing.Before it had some hardcoded values that would probably broke if anything changes, i saw it and solved. I wasnt here for it, i was fixing another bug and fixed it before it broke.
I also used some basic math of circles like angle of an arc. That is all for today
