* Fix double click to enter path tool * Fix error * Fix transform bug * Fix squaring scale on images * Shift node position and refresh graph * Downscale node seperate * Fix mirror * Remove duplicate transform * Always show node graph * Correctly set freehand and spline tool positions * Run cargo format * Maybe fix the scale * Downscaled image is always smaller than origional * Fix one crash * Don't show node graph on welcome screen * Reduce default graph panel height --------- Co-authored-by: Keavon Chambers <keavon@keavon.com>
