Fixes two related issues when changing user profile pictures: 1. **Image caching problem**: When selecting a custom image from files, the menu avatar wouldn't update without restarting Cinnamon. This was caused by St's CSS background-image caching - AccountsService copies all custom images to the same path (/var/lib/AccountsService/icons/<user>), so the URL stays identical while only the file content changes. 2. **Size limit**: AccountsService rejects images larger than ~1MB with a silent error, preventing large photos from being set as avatars. **Solution:** - userWidget.js: Implements cache-busting by copying AccountsService icons to ~/.cache/cinnamon/avatars/<user>-<mtime> with unique timestamps, forcing St to reload the image. Also resizes oversized images as fallback. - cs_user.py: Resizes large images (>512px) before passing to AccountsService, preventing rejection. Also fixes existing bug where original path was used instead of the resized .face file. Tested with images up to 9600x6000 (5.4MB) - now displays correctly without Cinnamon restart.

Having the user's avatar picture set as a background-image is nice because it allows us to round the image or add a border easily via themes, but when the user chooses a new image, it's not so easy to force the image to be updated, even though the StTextureCache notices the change and drops it from its own cache. This is mainly an issue when selecting a custom image from a user directory or a photo - AccountsService copies these to /var/lib/ AccountsService/icons/<user>. So, the file may change but the path does not, which keeps Cinnamon from updating it. Monitor the texture cache and recreate the avatar image entirely when it changes instead - this forces an entirely new actor and theme context for it, and gets the proper updated image.

After some research i think this fixes two related issues when changing user profile pictures:
Image caching problem: When selecting a custom image from files, the menu avatar wouldn't update without restarting Cinnamon. This was caused by St's CSS background-image caching - AccountsService copies all custom images to the same path (/var/lib/AccountsService/icons/), so the URL stays identical while only the file content changes.
Size limit: AccountsService rejects images larger than ~1MB with a silent error, preventing large photos from being set as avatars.
Solution:
userWidget.js: Implements cache-busting by copying AccountsService icons to ~/.cache/cinnamon/avatars/- with unique timestamps, forcing St to reload the image. Also resizes oversized images as fallback.
cs_user.py: Resizes large images (>512px) before passing to AccountsService, preventing rejection. Also fixes existing bug where original path was used instead of the resized .face file.
Tested with images up to 9600x6000 (5.4MB) - now displays correctly without Cinnamon restart. I hope this will help.
