Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Move functions into graphic engine layers. Cairo and Skia have their own header files and C/C++ files. Some functions are refactoried and move into graphic engine layer to make reset of MadButterfly independently from graphic engines.
