// Fltk unit tests
// v0.1 - Greg combines Matthias + Ian's tests
// v0.2 - Ian's 02/12/09 fixes applied
// v0.3 - Fixes to circle desc, augmented extent tests, fixed indents, added show(argc,argv)
// v1.0 - Submit for svn
// v1.1 - Matthias seperated all tests into multiple source files for hopefully easier handling
