Annotation typos and outdated meta information

Fixing annotation typos and outdated meta information requires edits to the [Defold source code](https://github.com/defold/defold/tree/master/engine), as this is the main source of documentation generation.

This issue is an attempt to collect that kind of bugs in one place and prepare pull requests to Defold batchwise. So feel free to share any annotation issues here. It will be more useful than fixing these bugs locally or just ignoring them.

Start by reviewing the Defold engine source linked in the issue, since it is the source for generated documentation. Look for annotation typos and outdated meta information, then collect concrete findings and prepare a batch pull request; the issue does not name specific files or tests.
