test/blocks: improve timer test code.
This commit does not change operative code but adds the ability to test the timer callback under Windows and improves the timer statistics. The code has been formatted in some parts, but not "everywhere". git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12352 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
