// BUG: If you drag the window, the dia show will stop playing, but the sound continues! This makes everything out of sync.
// TODO: When the windows is only resized a little bit (A few pixels), the window should not centered
// ... Calc the width and height of ALL pictures, and then size the form to the biggest value?
// ... or hard code the resolution in the INI file?
// Idea: Ini Parameter if fullscreen is applied or not
// Idea: Savestates, speedup, pause, Use Space bar to go to the next decision point.

// HOTSPOT_RELATIVE_ORIGIN is a new behavior which is not compatible with the original engine.
// With HOTSPOT_RELATIVE_ORIGIN enabled, the coordinates will be relative to the picture
// The original game has the origin at the top left corner of the screen.
// This is a problem because the game as well as the scene editor does not know the
// desired resolution, as it is automatically determined.
// If we would hardcode the desired canvas (640x480) in <ExeName>.ini, then
// it would work, but then, the scene Editor can not know the desired resolution...
