[python-win32] Have IHTMLWindow2 objectneed correspondingIHTMLWindow3 object and flash box

[Richard Bell]

I've cleaned up the flash code and am posting it as possibly helpful to
others.

Interestingly, I'm unable to find a way to SetROP2 in win32gui!  So the side
discussion about win32gui v. win32ui may be a bit moot.  If there is a way
I'd be curious to know what it is as it appears to me that there is a
SetROP2 method that is part of window's basic GDI library (but since I'm
definitely not a window's GDI programmer I could well be entirely wrong).

Thanks again for the help.

Regards,
Richard

BTW, the issue of finding the screen coordinates of the HTML tag turns out
to be VERY tricky.  I'm still working on a solution having discovered that
it depends on (among lord knows what other things) the presence of a DOCTYPE
declaration in the page source and nesting of scrollable windows within the
page.  If anyone is interested I'll post a solution when I find one that
actually works.
