VSCode doesn’t recognize classes imported from Processing libraries

[SableRaf]

When using a library in a .pde sketch, the VSCode extension doesn’t recognize classes from the library, even though the sketch runs fine.

Here, for example, I'm using the gifAnimation library.

Error message

"The name 'Gif' cannot be recognized"

Expected behavior

Library classes like Gif should be recognized and not flagged as errors in VSCode.

Steps to reproduce

1. Create a .pde sketch.
2. Import a Processing library (e.g., gifAnimation.*).
3. Try using one of its classes.
4. Observe that the extension marks the class as an error.

This might be a limitation in the LSP

Is that something we can fix?
