New features:
* More use of D's own language features, this will be improve even further in the future.
* WindowMaker for PPE/Concrete enables the creation of GUI elements. Currently it's in its very early stages, lot of functions are missing or don't work correctly, but it's made well enough now to help to finish itself, alongside PixelPerfectEditor.
* Some levels of parallelization in the rendering that works similarly to 3DFX's own SLI technology, currently has too much artifacting thanks to threading issues. Going to fix it soon, even if it only has some advantage with CPU rendering (GPU rendering will be done either through custom shaders, or through some form of GPGPU method, probably DCompute to make portability easier).
* Started working on its own audio engine.

Coming soon:
* Various ways of soundFX/music generation (FM, sample/wavetable).
* Sprite scaling/rotation/3D effects.
* Some way to reduce redraw calls and area, for GUI mainly.
* Multiple system support, including the Raspberry Pi.
