offer right-ctrl as a grab option
Add support for -ctrl-grab to use the right-ctrl button to grab/release the mouse in SDL. The multi-button ctrl-alt and ctrl-alt-shift grab buttons present an accessibility problem to users who cannot press more than one button at a time. https://bugs.edge.launchpad.net/ubuntu/+source/qemu-kvm/+bug/237635 Signed-off-by: Dustin Kirkland <kirkland@canonical.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
