Scrolling canvas speed

The example that comes with Xojo just scroll the Hubble image. If the same image is loaded, for example, with Graphic Converter or Preview, showing the same image size in the window, with the same zoom, the mousewheell is slower in the Xojo example. Tried with a bigger image is still much more evident.
Is there a way to speed the scroll to reach the same behaviors that those referenced apps?

In the ScrollingCanvas.MouseWheel event try adding a line at the top to increase the mouse wheel delta. For example:

deltaY = deltaY * 8

Thans this improves a lot the scroll
