   - If a character does not have this file, default settings are used. Most of the time, there is no need to customize the emotion templates per-character.
   - *At the client end*, only this one file is needed (or even supported) to customize the emotion templates.
 
-The **sprite position** on the screen is static. Due to the base pose used by the posing engine, the character's legs are always cut off at the bottom of the image, so the sprite needs to be placed at the bottom. You may need to create a custom background image that works with this placement. Of the default backgrounds, at least the cyberpunk bedroom works fine.

 **IMPORTANT**: Changing your web browser's zoom level will change the size of the character, too, because doing so rescales all images.

     Currently we don't have a way to set it installation-wide.
 - BACKEND: Fix timing of dynamic postprocessor effects, these should also use a 25 FPS reference.
+- BACKEND: Add configurable crop filter to trim unused space around the sides of the character, to allow better positioning of the character in **MovingUI** mode.
