>Summary: Clean up DHTML image loading
>
>Bugs Fixed: LPP-4910 - Images sometimes ignore view boundaries while 
>loading in DHTML w/ latest trunk build 6836
>
>Technical Reviewer: promanik
>QA Reviewer: hminsky
>Doc Reviewer: (pending)
>
>Release Notes:
>
>Details: Use __destroyImage() for image destruction to prevent DOM 
>leakage.  Show images after load in __imgonload() if this was a
>setSource() call.  Hide images before load in __getImage().
>
>
>Tests: Testcase for LPP-4910 now runs well in DHTML.  demos/lzpix/ 
>app.lzx?lzt=html&lzr=dhtml looks good.
