Low level console graphics library

This is a low level console graphics library, originally based on VGAlib 1.2 by Tommy Frandsen. VGAlib supported a number of standard VGA graphics modes, as well as high resolution/high color modes found on many popular graphics adapters. As of now, support for many more chipsets had been added.

It supports transparent virtual console switching, that is, you can switch consoles to and from text and graphics mode consoles using Alt-[Function Key]. Also, SVGAlib corrects most of VGAlib’s textmode corruption behavior by catching SIGSEGV, SIGFPE, SIGILL, and other fatal signals and ensuring that a program is running in the currently visible virtual console before setting a graphics mode.
