[PATCH] Make RDP backend supports arbitrary modes

Hardening,
By and large, I think it looks good. I have a few nit-picking comments
below that should take ~20 seconds to address.
I was trying to test it on my machine and nothing seems to resize. Is this
because the xfreerdp client doesn't support resizing or is it from some
other reason?
Thanks,

a) Missing the space between "if" and "(". Also, let's do if (!ret) return
NULL; It makes it easier to read.
