Brush Aspect Ratio Range
The brush aspect ratio should be easily understood, and predictable to use. A fine line should be achievable by creating a very squashed circle.

Normalized Aspect Ratio
Current Design: Range is from -20 to 20, 0 is undistorted, non-linear distortion up to 20 where there is a distortion clamp that limits the effect.
Issues: Historical reasons that are confusing in the GUI and confusing in the code.
Changes: An aspect ratio of 1 is undistorted, 0 is very distorted, -1 flips the brush stamp, linear distortion.
How to Use:
- Replaced the old non-linear aspect ratio range of
-20 to 20with a simplified linear range from-1 to 1 1means undistorted,0represents high distortion, and-1flips the brush stamp- Special handling for
0aspect ratio prevents problematic behavior, ensuring minimal distortion of0.005 - Updated brush editor uses
-1 to 1range with linear steps for finer control - PDB interface reflects the new range, removing old
-20 to 20bounds
Benefits: Simplifies brush aspect ratio behavior, making the interface easier to understand. The predictable linear distortion improves usability and allows finer control over brush appearance.
