CalculatePreferredSize is called from the GetPreferredSize method (in TControl)

<remark>
In previous LCL versions, CalculatePreferredSize did not use the WithThemeSpace
argument or adjust the preferred size when it was enabled. As a result an
auto-sized control would truncate the Caption displayed for a TSpeedButton
control. This behavior has been changed in LCL version 4.0. An auto-sized speed
button is now increased in size for theme spacing. This can lead to misaligned
buttons in applications or descendent classes which handled the condition
independently. Descendent classes may need to implement an overridden
CalculatePreferredSize method and reduce the preferred size by the pixels added
in the base class. Applications can use anchoring or aligning to align the
borders on speed button controls.
