apple function draws the apple of the radius r pxls for size = 1
there are 3 components:
1) main body
2) root, represented by a line
3) leaf, which is obviously a sqrt curve
The coords of root and leaf are given regarding to r of an main body,
so all "strange" numbers in the further functions are also just a calibrate number for beauty's purposes

mirror is for drawing mirrored images
