// Minimal update test program for the Fast Light Tool Kit (FLTK).
//
// This is a test of the minimal update code.  The right slider has a
// label that extends outside it's border, and the minimal update
// assummes this does not happen.  Thus there is *supposed* to be
// display errors when you move the right-most or any other slider.
// If you *don't* see these errors, then the minimal update is
// broken!!!
//
// I cannot emphasize how important it is to test this and make sure
// any changes have not broken the minimal update.  These sort of bugs
// are extremely hard to fix and must be detected right away!
//
// The reason it is important to fix this is that otherwise you will
// swiftly end up with a toolkit that thinks it has to draw the window
// 20 times each time the display changes.  I don't care how fast the
// machine is, this is an insane waste of resources, and should be
// stopped!
