annotate src/mouse.c @ 795:46a4cd4d382b

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Remove dependent on system time to gain frame rate Date.now() would read system time. It is ineffeciency in for some implementation. To gain frame rate, we should rely on accuration of setInterval().
