This event is fired during HTML rendering.
During the time that HTML rendering is taking place, progress
events are sent out to any event subscribers. This gives a
mechanism for tracking progress and for intercepting and modifying
or querying pages on the fly.
If the page is obtained from the cache,
then events will not be fired.
Note that the amount of work done during a progress event should
be kept to a minimum.
Current values for the stage variable are 'get width', 'get
height' and 'render'. The first event occurs prior to finding the
natural width of the HTML (the width it can occupy without
scrolling). The second occurs prior to finding the natural height.
The third occurs prior to translation into PDF format.
The page is provided via an IHTMLDocument interface - see
Microsoft documentation for details. However, note that while the
interface is standard, the behavior may not be identical. For
example, element positions may not be available.
If you want to handle HtmlRender events, you must declare your
Doc variable explicitly using the WithEvents keyword.

Please note that WithEvents variables must be module-level
variables and can only be placed in forms and other class modules.
