Viewer scaling 8/9 crash

[Sam]

This problem is due to the use of the StretchBlt() 
function for stretching the Win32 viewer window.
Sometimes, depending on the scaling factors and the 
window's size , the dimensions of the stretched rect 
can exceeed the dimension of the screen.
In this case, some video drivers just crash (wild 
reboot and checkdisk... and no data loss if you are 
lucky).

I'm only aware of this pb since a few days as I've 
added a new scaling feature to UltraVNC and it was 
rebooting anytime. I think I've found a very simple 
workaround to avoid this problem, whatever the video 
drivers and the scale factor.

It is implemented in Ultr@VNC RC1.09 that should be 
available next week :)
