[Laszlo-dev] [UPDATED^4] For Review: Change 20090130-ptw-t Summary: Implement LFC end of kernel scrolling API

[P T Withington]

[UPDATED^4: This incorporates Max's changes, with some tweaks by me.   
The basic difference from Max's version is that per the documentation  
he found, scroll and scrollmax are the line number of the _top_ line  
visible in the (clipped) field -- scrollmax _does_not_ include the  
height of the field (whereas scrollHeight does).

I updated scrolledittext to use the modern API's and the tests that  
Max updated seem to pass in swf8 and swf9.  DHTML is not working (yet).

If the reviewers can agree that we have enough working, I'd like to  
check this in before it gets any more unweildy.]

Summary: Implement LFC end of kernel scrolling API

Bugs Fixed: LPP-6580  scrolledittext doesn't work in 4.1 (partial)

Technical Reviewer: max (pending)
QA Reviewer: hminsky (pending)

Details:
     LzSprite.*, LaszloView, LaszloCanvas: Add linescrolling
     capability, unify capabilities as a sprite instance var.

     swf/LzTextSprite.as: Turn on warnUndefinedReferences so we can
     debug this.  Stop making all sorts of undefined references.
     Actually compute `lineheight`.  Use that to implement the
     pixel/line kernel API.  Convert __updatefieldsize to use the new
     scrollevent kernel API.

     swf9/LzTextSprite: Add primitive version of setX/YScroll

     LzInputText: Set tsprite in __makeSprite

     LzText: Implement new kernel scrolling API.  Cache tsprite for
     efficiency.

     newcontent, basescrollbar: Silence warnings.

     scrolledittext: Use new API's

     test/*: Max's improved tests

Tests:
     Compiles in swf9, smokecheck in 3 runtimes, component debugger in
     swf8/9, component sampler in 3 runtimes.
