Thanks for finding. This will add about 2 MB of tcz extension to the cairo.tcz install. Cairo is 500kb. What functions of cairo require this dep? Is it something that can be added to the info file as opposed to a hard coded dep?
Cairo lists it as follows, if I am correct. Is this just a debugging feature, and if so, can be recommended to add binutils in the info file?:
The first step in analysing any problem is constructing a reproducible test case. Cairo provides a cairo-trace utility (currently only available from the git development tree and in the 1.9.6 snapshot but also planned for inclusion with Cairo 1.10). This utility records all Cairo calls made by an application and allows you, and everyone else in the community, to replay the exact same sequence. This trace can be reviewed by others and they may be able to suggest alternative methods of achieving the same results. Or it may provide the developers with a useful benchmark for improving Cairo.
