Congratz !
I used your branch krita-fixed-transform-kazakov the past 10 days and became addict to it.
Also, since the 'warp' feature of the transform tool is fast , I don't need a 'Iwarp' filter anymore : I can tweak proportions, shapes , directly on the canvas.
I also love to play with the 'perspective' ( Press Control on a transformation and rotate on perspective ) it's now very fast to compute.
Also, R.I.P the ghost  :)
