changed (and the old window/device deleted) while the old device was still actively delivering events, so deleting caused a crash. Now changing the resolution is only setting a flag, and the resolution change will be applied during the next update, i.e. while the device is not busy anymore. git-svn-id: svn+ssh://svn.code.sf.net/p/supertuxkart/code/main/trunk@6707 178a84e3-b1eb-0310-8ba1-8eac791a3b58
