* This is supported currently in the API inspector, constant buffer previewer, and resource inspector.
* The saved expansions are only saved while the capture is open, and will be reset each time.
* The new function SetCaptureFileComments allows users to add comments to a
capture after creating it at any time.
* We also use anonymous union to remove the need to duplicate API structs for
backwards compatibility.
* This has some possible problems - e.g. if one copy of qrenderdoc is closed and
kills the server used by another copy. However it seems impossible to reliably
manage adb and we need to ensure we don't leave the process lingering around.
* At the moment 95% of users don't use android, so it's most important that they
have a smooth experience.
* This was the cause of problems around updating versions because adb.exe would
hang around and then be 'in use' and not able to be overwritten.
* The event browser called SetEventID from OnCaptureLoaded, which would then
call OnEventChanged on all viewers, which if they kicked off work could happen
at the same time as the later call to OpCaptureLoaded for them.
* In the mesh viewer this seemed to lead to a race condition and had a chance to
corrupt memory.
* When selecting a marker region, the more intuitive search is to find children
of the marker first before searching onwards, even if the 'current event' is
at the end of the marker region.
* In particular this means that it's safe to compare a ResourceId or similar
against None. It is always not-equal but it's useful to have the comparison
work and return the expected result instead of throwing a null reference
exception.
* Instead of having an N:N mapping of parts of variables to parts of registers,
instead we gather everything together under each variable and it has a list of
registers that comprise it.
* Any gaps are represented as undefined register mappings, for components that
aren't available in any register.
