[Vm-dev] Bigger cursors needed

I'm a little concerned that this will cause the entire vm-display-X11  
plugin to fail to load on any machine that doesn't have libXrender.   
Is there any way to implement this stuff without depending on  
Xrender?  Alternatively, are you absolutely sure every machine bigger  
than a wristwatch is guaranteed to have the Xrender extension?   
Alternatively, how about I add a 'configure' option that turns on  
this support explicitly?

Remember that (1) the OLPC isn't the only machine that uses an X11  
window and (2) most people download binaries with all of the  
dependencies screwed in as absolute requirements on their local  
machine for the VM to run properly.  Anything that we fix  
specifically for (1) must not degrade the experience or complicate  
life for (2).

Cheers,
Ian
