Started outlining how the modular driver set will look for video drawing routines. Currently supports Drawing pixels to the screen & Flushing backbuffer -> frontbuffer. Still very much test code, tracer is used everywhere for debugging, NOT DEVELOP READY. Many more draw routines need implementing - such as, but not limited to; drawRect, drawBitmap, drawLine, drawCurve, drawCircle. TODO: Implement the aforementioned routines in all VESA modes + WindowManager.
