Windows loading animation

WindowsLoad.java

/**
 * Code by Alexander Patlidanoski
 * This function draws the windows logo in the middle of the screen
 * and causes it to rotate on a central axis as though the Windows OS
 * is loading.
 *
 * This function contains a Push/Pop matrix, that changes the positon of the 
 * starting X (across) and Y (down) axis to be in the centre of the screen.
 *
 * int rot and rot = rot + 1 causes the boxes to rotate 1 pixel every time
 * the function is executed (which is infinate)
