Result of 90 degrees rotation is wrong

[Wetgos]

When I was programming a rotation event for a game,
I discovered that when I tell PowerDraw to rotate an image
90 degrees, the result is an image that is rotated approximately 30 degrees.
I have a simple (Delphi) function to solve this.

function DegToPower(Angle: Real): Extended;
begin
  Result := (Angle / 360) * 256;
end;

I hope this makes the implementation of the rotation feature of PowerDraw easier.

I suggesto to change directly the PowerTypes unit in the pRotate4 procedure:

 // convert angle to radians
 //Beta:= (Angle * Pi) / 128;

to:

 // convert angle to radians
 Beta:= (Angle * Pi) / 180;
