This function allows copying a capture so that we can do
additional reads. This does, however, copy the buffers which
might be more memory than we want for large usage. We can
tweak things as we go to figure out the cursors.
We keep the start time as a iso8601 string, which is useful, but not
enough for relative timestamps to the epoch (start time). Include a
clock time in the same clock domain.
We might want to add a CTRADD type later on, for relative values rather
than absolute. But this should get us started.
Simply define counters upfront, and then set them during the capture
process.
Obviously, we need to come up with a good way to visualize this
information in the UI.
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.
