annotate Android/java/org/madbutterfly/redraw_man.java @ 528:d687d3395264 Android_Skia

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Clear variables and draw root coord. Although root coord is never in zeroing list, now, it still need to be redrawed after redrawing other zeroed coords.
