[cairo] Compiling for Cairo development

[Bill Spitzak]

Any recommendations for how to compile Cairo when I want to work on 
Cairo itself? This is on Ubuntu 10.04.

What I would like to do is be able to modify my git checkout of Cairo 
and test the results.

Right now I have to "sudo make install" after compiling any changes. I 
would prefer not to do this as I don't want to risk messing up other 
programs that use Cairo.

I believe I can avoid this for Cairo itself by building my test programs 
linked directly to cairo/src/.libs and pixman/pixman/.libs. However 
changes to pixman look a lot more risky. Cairo refuses to compile unless 
pixman is installed.

It would seem that Cairo developers must be doing this already, are 
there any recommended procedures?

Also the instructions for compiling need to point out that pixman must 
be done first, and pixman needs to point out that autogen.sh must be run 
if you check out from git. I don't think a newbie could ever get past 
this to a compiled version of Cairo.
