We dont support vga text mode currently. I might add it later if needed.
I also removed mouse 'support' from Shell since it didn't do anything
and I didn't implement arbitary bitmap rendering to framebuffer

This allows us to not read from video memory, since it was very slow
I also implemented fast path for graphics clearing and scrolling if bpp is 32
