Brush size in %% to the selected area

[Nighternet]

If elasticity brush can work in %% to the selected area, why can't the main brush do the same. That's what I was asking all along, since brush size set in pixels doesn't work the same in various resolutions and magnifications.

That is because elastify brush is round, so we dont need a bitmap to process it, it can be any size and it will have always the highest quality..
Brush in painting tools is usually „image stamp” based, so it is limited to certain size in pixels. Besides enlarging it will is like image scaling - it becomes blurry.

However making it in % is possible...
