Details:
>From reading the code, it looks as if the xtilt and ytilt inputs are not
rotated to compensate for the rotation of the canvas at any point before
mypaint_brush_stroke_to() is called. This doesn't seem right to me: it breaks
the analogy of the rotation commands being like to rotating the drawing on the
desk before placing one's pen.
Thus if I rotate the canvas 45 degrees clockwise (by invoking "Rotate
Clockwise" or Ctrl+Right twice), the values passed on by the tdw for xtilt and
ytilt should be altered as if the vector (0,0)->(xtilt,ytilt) were being
rotated 45 degreed anticlockwise while preserving its magnitude.
Sadly I don't have a tilt-sensitive tablet to try out a fix for this :/
