Fixed bug 2866 - testrelative.c: patch to make the orange box wrap around

Browse source 
Eric Wasylishen

Here's a patch to make the 'testrelative' demo program more useful: it just makes the orange rectangle wrap around. Previously, the orange cursor would just disappear off screen if you move the mouse a lot in one direction, so it was hard to tell if relative mouse mode was still working.
