[Golist] This looks a bit better as far as syntax

[Karsten Goetz]

Hi John,

i tried somthing like this, too. I've post it on playground here:
GoPlayground/KarstenGoetz/src/de/karstengoetz/tests/TgoTween.as
It's nearly without comments and I did not make a wiki entry, too  
( sorry... ).
The intention was to keep the init-possibilies of a tween open, and I  
came up to use a arbitrary class ( i call them VO for value  
objects  ), too - and leave the possibility to use quick objects.

Init an VO-object would simple look like this:
			var startFormatVo : TextFormatVO = new TextFormatVO();
			startFormatVo.size = 1;
			startFormatVo.letterSpacing = 50;
			startFormatVo.leading = 10;

And it could be used in different ways like this:

	// if startvalue is null, the tween takes the instance parameters
	group.addChild(new ClipTween(textField, null, {alpha:1}, 0, .4,  
Linear.easeIn));
	// start and endvalues as objects, most common and quick use...
	group.addChild(new ClipTween(textField, {y:200}, {y:50}, 0, 1,  
Bounce.easeOut));
	// start and endvalues predefined with value objects
	group.addChild(new TextFormatTween(textField, startFormatVo,  
endFormatVo, 0, 1, Bounce.easeOut));
	// start defined inline with the value object, endvalue defined with  
a DropShadowFilter( returned from endFilter() ). Only the tweenable  
values of the  DropShadowFilter will be used
	group.addChild(new DropShadowTween(textField, new DropShadowVO(10,  
50, 0x000000, 1, 50, 45, 20), endFilter(), 0, 1, Linear.easeNone));

if you're pretty sure what properties to tween you can use {alpha:1},  
for complex animations or for storeing animation values you could use  
the vo-objects.
If you have to set a only oneway-used dataset you could use new  
VOObject(10, 50, and so on) and your editor would give the value-hints.
			
I created an array in the VO-classes and tried to use this one in the  
tweenclass itself for setting the properties or for the overlapmonitor.
But this stuff is not finished and I have to bring up wiki ( i  
promised so ;- )

I'm not 100% sure if this fits into the discussion, but these are my  
thoughts about spliting properties and tweenclasses. I like the idea  
of arbitrary classes!

Greetings
Karsten
