WindowOverlay

A (windows only) plugin to give your Simba script ability to draw on top of any window:

Basic example:

{$loadlib libwindowoverlay}

var
  Overlay: TWindowOverlay;
begin
  Overlay := TWindowOverlay.Create(); // `TargetWindow` not specified. Will Simba's current target.
  AddOnTerminate(@Overlay.Free);

  // Overlay.Bitmap is a TMufasaBitmap, let's draw a red rectangle.
  Overlay.Bitmap.Rectangle([100, 100, 200, 200], 255);

  while True do 
    Sleep(1000);
end.

• The overlay automatically paints every 100 milliseconds, this can be changed with the PaintInterval parameter in the TWindowOverlay.Create method.
• If doing lots of drawing at once, do your drawing between a BeginUpdate and EndUpdate call to reduce flickering.
