I think I figured that one out already. The times for just the StrokeLine 
calls are exactly the same for drawing inside and outside the clipping.

When I run both the Dano version and the testenvironment version of my 
program in strace, it seems like neither of them is using syscalls for 
communicating with the respective app_server. I get a lot of output when I 
launch or quit the programs, as well as on focus changes, but not during 
the redraws. Am I doing something wrong?

Best regards,
