// i.e when splitter is moved from 2 to 8 it should be inserted at 9
// but when it is moved from 8 to 2 it should be inserted at 2 .
// Some explanation ...(Strange .net behavior !!)
//Say that we have 5 splitter(s1..s5) and panels (p1…p5) , with z order as shown
// Move from 2 to 8 :
// p1, s1, p2 , s2 ..... p5, s5
// Now when we move p2 (at 2) to index 8 , all the controls after index 3(s2) to index 8(p5) will be moved upward by 1.
// p1, s1, s2, p3, s3, p4, s4, p5, p2 ,s5 (not expected behavior)
// Now as you can see when we move from 2 to 8 , P2 is inserted between P5 and S5 which is not desired behavior for us.
//So, we need to insert P2 at index 9 and then S2 at 9 again so that splitter and panels remain together.
//Now consider the case when we move from 8 to 2.
//When we move from 8 to 2, all controls from 2 to 7 are moved downwards.
// So controls are :
// p1, s1, p5, p2, s2, p3, s3, p4, s4, s5 (expected behavior )
// (If we will move at 3 using +1 logic it will result in incorrect behavior )
