annotate src/mouse.c @ 509:3e0d63d7c7ae Android_Skia

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Remove absolute pathes from config.cache. Absolute pathes in config.cache would be the source of problems when the source tree of Android is different from what is in config.cache. So, these cached values are removed and re-computed when running configure.
