Progress Bar doesn't wrap value when out of range

When to position of the progress bar is greater than the maximum value or less than the minimum value, it should wrap the value. Currently, it just sets it to the minimum value and starts over.

Example:
PBM_SETRANGE32 = 0,10
PBM_SETSTEP = 3
PBM_STEPIT
0,3,6,9,2,5,8,1,4 etc., correct wrap (Windows)
0,3,6,9,0,3,6,9,0 etc., incorrect wrap (ReactOS)

(This doesn't apply to PBM_DELTAPOS which doesn't wrap.)
