Summary: QCCompositionParameterView controls get deformed when the containing view is resized.

Steps to Reproduce: Create a QCCompositionParameterView that is set to resize with the containing view (struts/springs, or whatever they're called now).

Resize the view, and watch some of the controls get stretched improperly (this is especially apparent with QCNumberPorts that have a max and min set -- a slider is generated that often slides under the value textbox).

Expected Results:  The controls should all scale properly, and absolutely never overlap/underlap.

Actual Results:  The controls sometimes under/overlap (especially sliders)

Regression:  This happens on Leopard (10.5.8 and earlier) through 10.6.2.

Notes: This makes QCCPV completely useless in contexts where it needs to resize dynamically -- it looks very bad.

Attached is an XIB that exhibits the problem -- open it in IB, start the simulation (cmd-R), and then resize the window.  Eventually the slider's right end ends up under the text box.
