60491a64cf Cirrus: Added horizontal pixel panning support for 8, 15 and 16 bpp modes. 
Original Cirrus VGABIOS uses this feature in VBE function 0x07 since the
screen start address is dword aligned. It's only documented for standard VGA,
but not for the extended Cirrus modes.
TODO: Implement this in the LGPL'd VGABIOS.

Fix big-endian support in bx_banshee_c::mem_read (#354)

QEMU PowerPC emulation:
