Summary: Create click containers only as needed
Bugs Fixed: LPP-6892 - Generated File Sizes baseline complete; Performance
Tuning ongoing
Technical Reviewer: ptw
QA Reviewer: hminsky
Overview: This change only creates click containers for clickable sprites.
This drastically reduces the number of divs for each application.
Details: LzSprite - When addChild() sees a child sprite that has a clickdiv, it
creates a clickdiv container tree and appends it. setClickable() creates a
click tree as-needed. All setters, e.g. setX() only update the click div if
present. __updateClip() now tracks clip css in the _clip attribute.
setContextMenu() now uses the __createContainerDivs() to create container divs.
__copystyles() tries to avoid copying unneeded styles and uses cached sprite
css values.
LzTextSprite - Don't create click divs.
LzInputTextSprite - Delay creating click divs until they're needed.
Tests: All apps run as before (but faster) in dhtml.
