winex11.drv: Add support for legacy resolutions using XRandR 1.3 affine
transforms.

Hi Aaron, thanks for the advice.  I've put together a patch that does this
using XRRSetScreenSize and XRRSetCrtcTransform and it finally doesn't cause my
X server to crash ;)  The way I'm doing this currently is using the matrix:
dw/nw   0   0
  0   dh/nh  0
  0     0   1
where dw = desired width, dh = desired height, nw = native width, nh = native
height

This makes the entire screen filled with the requested screen resolution
(stretched), which should be good enough for now.  However, I like the
aspect-ratio maintaining behavior that nvidia-settings does when you use scaled
resolutions like this.  Is there an easy way for me to maintain the aspect
ratio and have black bars on the sides instead?
