xscope is so damn useful.
Here's a patch to make it support the SHAPE extension. It'd be really good to get this thing into freedesktop.org and so people can hack on it to make it sane.
I should try out Soeren's gtk xscope wrapper.
I'm not sure what's the best way to build the thing, but if you check it out from keithp's CVS and do:
$> imake -I/cvs/xorg/config/cf
$> make
then it seems to build just fine if you remove the malloc() prototype
in common.c. Of course, if you have a space between the -I and the
path to the xorg build on the imake command line, then you could find
yourself spending a long time trying to figure out wtf is wrong.
Oh, yeah, one final tip. xscope is a proxy Xserver. So, when you connect
your app to xscope, Xlib goes looking in ~/.Xauthority for an xauth
cookie to use when authenticating. Because xscope has a different
display number from the parent display, though, you need to use xauth to
setup the cookie for this display number too. So, assuming the parent
display is :0 and xscope is :1, you can do:
$> xauth list | grep '/unix:0' | while read display proto cookie; do xauth add ${display%0}1 $proto $cookie; done
