This patch adds optimized routines for video modes using BGR/BGRA color
format.  Most PC video cards use BGR (24-bit) or BGRA (32-bit) color
modes, so this is an extremely important change and provides a massive
performance benefit.

I also renamed the R8G8B8A8 and R8B8B8 modes to RGBA8888 and RGB888,
etc., since it began to be highly unreadable when B8G8R8A8 was added
into the mix.  It seems that having the color components (letters)
grouped together in the name makes it much easier for me to determine
the mode name at a glance.

Regards,
Colin

	VBE performance optimization.  Added optimized rendering functions for
	BGR/BGRA render targets.

Thanks for the patch. I have committed similar version to SVN.

I made some changes there so apologies if it broke something in between.
I was only able to test it on qemu and it was ok there, but that is far
from complete test. So please test it on real hardware with different
cards and if problems are found report them back.

Thanks,
