fix endianness problem sharing the videoram buffer
[ The following text is in the "UTF-8" character set. ] [ Your display is set for the "koi8-r" character set. ] [ Some characters may be displayed incorrectly. ] This patch fixes vga rendering when the guest endianness differs from the host endianness: in this case we can only share the buffer if the bpp is 32 and we must change the pixelformat accordingly.
