Why does this need to be here?

[Nayan, 2013/01/15 23:39:03]

We use kTestWindowWidth and kTestWindowHeight in both shell.cc and
shell_aura.cc. Hence moved this variable to shell.h file.

Ok, make sense.

methods are before members. Additionally name arguments, and names should be the
same in declaration and definition.

Done.
