 #### Enhancements
 
 * The standard uniforms of all shaders have been updated: The window size is now passed as a `vec2` and there is a new `bool uForOpening` which is set to `true` if a window-open animation is ongoing, to `false` otherwise.
+* Refactored how the size and opacity transitions of the window actors are set up. Effects can now only specify a desired actor scale which will not change during the animation. All dynamic scaling and fading must be implemented in the shaders now.
