comparison vdp.h @ 1881:55198fc9cc1f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Don't render lines that are cropped by overscan. Allows submitting frame earlier when bottom overscan is non-zero which can reduce latency in some cases
