Synfig Studio full changelog

Features:
Sketch Tool: Added redo functionality for the sketch tool.
Converter: Introduced an Absolute Converter for angle/integer/real values.
Color Correct Layer: Added a saturation parameter to the Color Correct layer.
Bug Fixes:
Bevel Layer: Added a null check for sub_task to prevent assertion failure when no layers are below.
Add-Skeleton-Simple Plugin: Corrected the switched naming of "forearm" and "arm".
Gaussian Blur: Fixed the vertical pass for gaussian blur.
Refactoring & Chores:
Avoided copying variable on left-rotating vector.
Removed CanvasView methods unused since 2005.
Fixed synfig::filesystem::Path test for compare method.

Feature Enhancements: Several new capabilities have been introduced, such as an angle converter that supports integers, hotkeys for locking/unlocking past and future keyframes, a new 'Alpha Intersection' blending mode, and enhanced palette clipboard functionality. Additionally, initial support for SVG Text elements and Lottie Text Layers has been added.
Stability and Quality Improvements: Numerous bug fixes address critical issues including rendering artifacts in outlines, undefined behavior during undo/redo operations after value conversion, crashes related to malformed PNG imports or null devices, and various UI/UX inconsistencies. Specific fixes include improved SVG importer behavior, corrected bline tool interactions, and resolution of font rendering issues.
Performance and Code Refinements: Significant refactoring efforts have been undertaken, including the porting of several layers (Bevel, Noise gradient, HalfTone2 & 3) to the more efficient Cobra rendering engine. Other improvements include optimizing code for image sequence import, enhancing parameter passing by reference, and general code style cleanups.
