Link to original bug (#164837)
Description
pressure slider of the airbrush tool (I am not talking about hw pressure info from a tablet) located in its option dialog has somewhat strange scale. all the variation seems to be concentrated in its left half or so; from the middle to the end giving the same results. it is both untituitive and makes adjusting pressure harder and less accurate
