* The converter program will be able to open old captures, but is itself
captureable in new renderdoc builds. This isn't a direct conversion
but should allow a reasonable estimation and is better than nothing.
* NOTE: The resulting converted file will have no thumbnail, and no
callstacks (if they were present before). As well as more minor things
like backbuffers no longer appearing identified as backbuffers, some
markers losing their colours, etc.
* Tacking -official onto the git hash was a hack only needed on windows,
and since we want more information it doesn't scale.
* Instead we track anything we need to know about the version in
separate variables, like whether it's a stable build or a nightly/
local build. Or if it's built by a downstream distribution then the
version number for the downstream build.
