Version:           svn trunk (using KDE 4.4.5) 
OS:                Linux

when drawing with experimental/shape brush, if you look very close, you'll see the shape is shaking a little while drawing it (it shakes between 2 pixels, or something like that)

Reproducible: Always

Fix shaking of the experiment/shape brush

The problem was float coordinates and rounding.

Here it still shakes a little while drawing.
Maybe it shakes a little less (I'm not sure), but it still is :/ .
Comment 5 LukasT 2011-12-31 11:49:53 UTC 
It used to shake for me when I was changing the position of the stroke's top-left corner.

How do you reproduce it?
Comment 6 animtim 2011-12-31 12:25:55 UTC 
To reproduce I used to draw random circles (counterclockwise).
So now after your comment about top/left I notice indeed it shakes only if
the strokes goes to the top and/or the left.
Comment 7 animtim 2011-12-31 16:54:00 UTC 
Ok I had an update issue, now it doesn't shake anymore indeed.
Bug fixed! :.)
