Fake screen resolutions in kkapture

The small tool kkapture by ryg of Farbrausch is the only sane way to get a video dump of demos, intros and similar stuff. By grabbing all video and audio output directly from their respective APIs (OpenGL/Direct3D and WinMM/DirectSound) and simulating a fixed time base for the client application, it produces perfect-quality smooth video files suitable for Blu-ray Discs, for example. kkapture doesn’t alter the demos in any other way, though – in particular, the screen setup code from the demos is left untouched, with the result that it’s not possible to kkapture most demos in resolutions higher than the display currently attached to the computer. I did a little modification to kkapture’s code that changes this and allows things like 8-megapixel kkaptures.
