annotate vgm.h @ 1971:80920c21bb52

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add an event log soft flush and call it twice per frame in between hard flushes to netplay latency when there are insufficient hardware updates to flush packets in the middle of a frame
