print_pixel only used once now
go ahead and put in it main. no loss of readability really.
don't die on SIGPIPE
this will allow `stint | sed q' to exit with a 0 return status, and also
to wait for the button to be released
simplify logic for releasing button
whoops, forgot to update readme yesterday
address compiler warning
return status 2 if color selection was canceled
should aid in scripting
remove imlib2 dependency!
inspired by grabc's method of getting colors

press a different button to cancel
also waits for that button to be released so the underlying window
doesn't get a random ButtonRelease event
make print_pixel static so it can be inlined
add gpl and boilerplate
initial commit. it works.
