[Laszlo-dev] [UPDATED^2] For Review: Change 20090130-ptw-t Summary: Implement LFC end of kernel scrolling API

[P T Withington]

[UPDATED^2: The swf8 debugger is working a bit better now.  There is  
still a slight error in going through the new interface, surely  
related to André's comment regarding taking the text gutter into  
account when measuring scrolls.]

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: Silence warnings.

Tests:
     swf9 compiles
