yes, i tried that patch/branch
sadly, it's as useful as the so-called "scaling" option in microsoft's rdesktop, that is, totally useless.
not your fault, obviously, but it works only against very recent terminalservers, and is completely useless, since it doesn't really scale up the desktop, but changes settings on the server side, which is yet worse, if possible...
that branch is working as expected, though, but i could try only against one server, so i don't even confirm that's working at 100%...
sorry
do you think is possible to -and at which point in rdesktop sources- insert a scaling function between server and client rendering?
