Sorry. The last time I tried to close this review, ReviewBoard crashed. Will try again. :)

> Currently, KGameRendererClients are created with a default renderSize of 3x3. This patch changes the default to an invalid size so that no rendering is done until a valid renderSize is given. This both saves some totally unnecessary rendering and is more likely to match the expectations of users of KGRC.

The issue was intermittent due to a race condition between the KGameRenderer's threaded rendering and Qt's delayed painting making it tricky to track down. Anyway, once I found the source of the 3x3 size, the issue was easy enough to work around, but I'd rather not see other devs hit similar issues.
