No -- Affine2D is for mutable transformations, and a ScaledTransformation is automatic (it really doesn't make sense to clear it). The real bug here is that the auto layout code has grown stale. It should probably remove it, since it was basically an aborted experiment and I don't want to create confusion. It turned out to be too difficult (perhaps impossible) to do the right thing in the general case given the current MATLAB-based APIs for laying out a figure. The real solution will need to provide a new API (which would be an alternative to the current one) that works somewhat like the box layout APIs in many GUI toolkits. Once I got to that point, I realised that would take more time beyond what I had allotted. > > Regardless of the status of the autoLayout code, I thought it would be > nice to improve the default title behavior of the polar_demo, at least. I've changed it so it behaves identically to 0.91.x, which is not great (since it puts the title too close to the edge of the figure), but at least it isn't a regression.
