Some first parts of this library are now available. There is:
* KgvTheme and KgvThemeProvider, the generalized form of KGameTheme
* KgvRenderer, a renamed version of KGameRenderer (with the custom colors 
stuff and the primary view stuff stripped out; both things will be done 
properly later)
* KgvConfigDialog, which includes an updated version of the KGameThemeSelector 

The code for the library is available from [1], and attached to this mail is 
an example application [2], which shows how easy to use the stuff in 
libkgamevisuals is (note esp. how the renderer automatically picks up themes 
which are selected in the config dialog).

My short-term roadmap for libkgamevisuals is:
1. design and implement KgvBoard, as a superior replacement for the automatic 
rescaling in KGameRenderedObjectItem (aka KgvSpriteObjectItem)
2. combine KGameSvgDocument, KSpiral's SvgReader, and some stuff from QtSvg 
into a QSvgRenderer on steroids, as a much superior replacement for the 
aforementioned components and the QPaintDeviceColorProxy

Though the second point sounds complicated, that's actually the low-hanging 
fruit. I also want to do an interaction framework which scales to different 
form factors and input methods (something like what I've done in Palapeli, 
though this one has serious design flaws and limitations).

And even more important, we need a concept how our interface can adapt itself 
to devices where KXmlGui is not the right solution. I think we'll need to 
abstract KXmlGui at some point, to be able to exchange that for on-screen (as 
in: on the QGraphicsView) controls like in KBattleShip.

Okay, I'm really going to finish the mail now. I'm sorry if this is going too 
fast for you, but the code is just flowing out of my hands into the editor, 
and I can't do nothing about it.

Greetings
Stefan
