Tests:

Local (Electron) app:
- Cloud project, 2D editor:
  - Can modify an image with Piskel and see the modified image (for a Sprite)
  - Can modify an image with Piskel and see the modified image (for a Bitmap Font)
  - Can modify a file of a resource and see the modified image (Sprite/Bitmap Font)
  - Can set a wrong file for a resource and see the invalid texture (Sprite/Bitmap Font)
- Cloud project, 3D editor:
  - Can modify an image with Piskel and see the modified image (for a Sprite)
  - Can modify an image with Piskel and see the modified image (for a Bitmap Font)
  - Can modify a file of a resource and see the modified image (Sprite/Bitmap Font)
  - Can set a wrong file for a resource and see the invalid texture (Sprite/Bitmap Font)
- Local project, 2D editor:
  - Can modify an image on the file system and see the modified image (for a Sprite)

Custom object tests:

(Local app) Custom object with a bitmap text, after the bitmap font atlas is modified on disk:
- Rendering ok in custom object editor
- Rendering ok in scene using the custom object
- Rendering ok in custom object editor (3D editor)
- Rendering ok in scene using the custom object (3D editor)

Multiple scene tests:

(Local or web app) when 2 scene (with 2D editors) are opened:
- No crash when adding a new sprite from the asset store or bitmap text

Multiple resources pointing to the same file:

(Local or web app) loading should work when a resource is changed to be the same file as another:
- Sprite
(Local or web app) no crash when two resources pointed to the same file as one is set to an invalid file

Basically, have to be robust against:

N resources pointing to the same file (both for reload and for unload).
Multiple objects using the same resource.
Multiple scene editor launched at the same time.

and we have to trigger reloads on:

File change for a resource (ResourcesEditor)
External editor used (xxxExternalEditor)
(local app only) file changed on file system (ResourceWatcher)

…e change

When 2+ SceneEditors are open, a resource change notification is sent to all editors, each calling reloadResource for the same resource. The second reload would unload the texture just freshly loaded by the first, destroying textures that active renderers in the first editor were already using. This caused "invalid texture" errors for BitmapFonts and null texture crashes for Sprites. Deduplicate per-resource reload requests: if a reload for the same resource is already pending, await the existing promise instead of queuing a new one. https://claude.ai/code/session_016DxEMZRcWFM8jZZhNuEBYV

…g the same file

We might always reload project data here?

this if seems useless now, and the method above does roughly the same (except different reason)
