Update cocoa.m to match new DisplayState code (Samuel Benson)
Version 2 does as follows: [1]: Corrects endianness on issues by using native BGR to RGB conversion [2]: Uses DisplayState accessors for obtaining graphics context information, which [3]: Removes now unused variables, and [4]: Allows reading of varying color modes (32bit/24/16), and converting to native colorspace [5]: Attempts to keep itself centered on screen (as opposed to bottom right, which immediately goes off screen after bios load) on context changes (window resizes) Testing working on i386 (gentoo, Windows 2000) and PPC (debian) guests on PPC and x86 Macs. In regards to [4], Windows 2000 displays fine on quick tests, but on the lowest setting I could test, 16bit color depth at 4bpp, colors are slightly off. I used gentoo install-x86-minimal-2008.0 in framebuffer mode to test above setting; the usual grey text is now blue, and Tux appears to be BGR shifted. I do not know if previous code worked at such a low color setting.
