These require you to run Steam.run_callbacks() in your _process() function to receive them.
- A screenshot successfully written or otherwise added to the library and can now be tagged.
- Sends back the following data:
- handle (int)
- result (int)
- handle (uint32_t)
- result (uint32_t)
- A screenshot has been requested by the user from the Steam screenshot hotkey. This will only be called if hookScreenshots has been enabled, in which case Steam will not take the screenshot itself.
