// Monologue Trees Editor
//
// Editor for creating Monologue Trees levels
//
// BUGS:
// * Cannot view scene when selected, WTF
// * Scene and Animation tabs are whacked
//
// TODO:
// * (medium) Spawn gltf scene
// * (medium) Load default scene when gltf selected
// * (medium) Set gltf to active/inactive
// * (medium) Play individual animation(s)
// * Only select one at a time.
// * (hard) Better Colorscheme
// * (medium) Visual errors for bad GLTFs
// * (medium) Spawn clicked scene
// * (medium) Play clicked animation
// * (easy) Play all animations
// * (medium) Add fonts similar to Audios based on inspect-fonts
// * (hard) Add Dialogs (requires text box UI, saving, loading).
//
// Asset types:
// * Audios (done)
//   * Loop individual
//   * Stop all
// * Gltfs (doing)
//   * Scenes
//   * Animations
//      * Play/Pause all
// * Fonts
// * Monologues
