[Laszlo-dev] Need input on LPP-8441

[P T Withington]

So, I'm digging myself in deep to your hints about how see LPP-5435  
and LPP-8219 might be affecting this cursor problem.  There's a huge  
amount of mechanism there to try to work around <input> elements in  
front of <img> elements.  It would be really nice to be able to  
eliminate that if possible.  It would be a real simplification...

At the bottom of it all is the way we put a resource on a view.  We  
create a subsidiary <img> to the view and then set that <img>'s src  
and background-image to the url of the resource.  I think that the  
difficulty in IE with text and clickable might be because the mouse  
events are leaking through to that <img> and there is a default  
browser action on <img> tags.

So I wonder, why do we need this subsidiary <img> element to give a  
background to a view sprite, when we could instead just use the CSS  
background-color and background-image attributes to put the background  
directly on the view sprite div.  A simple experiment shows that does  
_not_ interfere with the <input> element, indicating we could possibly  
do away with the quirks introduced for 5435 and 8219.

So, I need some background on why we have the subsidiary <img>  
element.  Was it just to parallel the swf structure (which I believe  
was to actually work around a bug in swf5!), or is there some DHTML  
reason?
