Its more matter of the user interface.

Given that the user has likely imported the bitmap into a graphics 
program to rotate it to the
correct orientation, and to crop it, I don't think it is unreasonable to 
expect them to adjust the
scaling as well before using it with Kicad.

I've been using two underlays on Windows and it has not been a problem. 
I've only
tried it on Linux in VirtualBox, and it was quite slow when zoomed in, 
but I'm not
sure if that was due to the virtualization or something in the wx bitmap 
handling
on Linux.
