The point of this file was to be easily usable by applications that want to generate capture files (or proxy them). The intention here is that we only have SpCaptureReader/SpCaptureWriter (and associated bits necessary to support that). This makes sure that we do not use GObject from the libsysprof-capture-2.a while still having GType's in the libsysprof-2.so dynamic library. We also invert the GObject macro check so that the default is to not register a GType which increases the chances that copy/paste code does not run into double-registering a GType if used with an application that links against libsysprof-2. (One such example could be if Gtk uses this code for timers, as it would break Sysprof itself).
