This API helps us simplify some of the tooling to iterate
through a capture. In particular, we might want to setup a
bunch of matches and then just iterate through the items.
This can also allow delaying the iteration until the future
which might be handy for visualizers which won't want to block
the main loop.
I'm not jazzed about the 64k buffer created for every cursor
due to the SpCaptureReader copy, but it's probably not a big
deal in practice until we start doing more exotic things.
This will make it easier to support installing just sysprof-cli and the
sysprofd helper daemon on systems where GTK is not feasible or necessary.
This does not, however, do that. It simply gets things broken up into
pieces.
This is a major redesign a modernization of Sysprof. The core data
structures and design are largely the same, but it has been ported to
Gtk3 and has lots of additions that should make your profiling experience
smoother. Especially for those that are new to profiling.
There are some very simple help docs added, but we really need the
experts to come in and write some documentation here.
