The ZoomLevel property changes the zoom level of the
current browser window to the specified percentage. A zoom level
of 100 represents the default size with no scaling
applied. Larger values magnify the content, while smaller values
reduce it. The zoom percentage is constrained by the limits
defined for the control. The minimum supported zoom level is
25 (25%) and the maximum is 400 (400%).
If a value outside of this range is specified, it will be
clamped to the nearest valid zoom level.
Changing the zoom level affects how the page content is displayed
but does not alter the underlying document. This is equivalent to
adjusting the zoom in a standard web browser. The new zoom level
applies to the current browser instance and will remain in effect
until it is changed again, or the control is destroyed.
The value of the AllowZoom property does not affect your
ability to change the zoom level using this property.
