Follow-up Comment #8, bug #19988 (project mypaint):
Possibly the brush was too weakly sensitive to tilt (I made it not knowing how
ascension and declination are derived from tilt...) or partially and slowly
dependent on direction or something. Difficult to tell, but give the attached
brush a try: its dab angle should match the turn of your stylus, broadstroke
style, and its ratio should top out to knife-edge at under 30 degrees of tilt
down from vertical.
Attached image is mouse-drawn, with a faked tilt of (x=-0.5, y=0.5). Dot in
the middle and stroke outwards while holding the rotate keys: mindless fun,
but I think it demonstrates that the correction's happening correctly. I think
the theory and implementation are sound at this point, but now I really need
to get a tilt-sensitive tablet to evaluate the feel of these brushes for
myself. Expensive hobby, this :)
