I spoke too soon in my previous response. I eventually found that by
using Paint to rotate the image 270 degrees, then doing a vertical flip,
then running the resulting bmp through fntcnvtr.exe, I am able to
directly dump the resulting bytes into the display and it works!

Thanks to those who responded!
