_windowed_mouse 0 on windows is basically identical to mono-touch on android, at least the touchless emulator. :) This needs testing on other platforms. Committing so I can easily get my source onto loonix. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4126 fc73d0e0-1445-4013-8a0c-d673dee63da5
