// presentation of native widgets consists of two important methods:

// AquaSalGraphics::getNativeControlRegion to determine native rectangle in pixels to draw the widget
// AquaSalGraphics::drawNativeControl to do the drawing operation itself

// getNativeControlRegion has to calculate a content rectangle within it is safe to draw the widget. Furthermore a bounding rectangle
// has to be calculated by getNativeControlRegion to consider adornments like a focus rectangle. As drawNativeControl uses Carbon
// API calls, all widgets are drawn without text. Drawing of text is done separately by VCL on top of graphical Carbon widget
// representation. drawNativeControl is called by VCL using content rectangle determined by getNativeControlRegion.

// FIXME: when calculation bounding rectangle larger then content rectangle, text displayed by VCL will become misaligned. To avoid
// misalignment bounding rectangle and content rectangle are calculated equally including adornments. Reduction of size for content
// is done by drawNativeControl subsequently. Only exception is editbox: As other widgets have distinct ControlPart::SubEdit control
// parts, editbox bounding rectangle and content rectangle are both calculated to reflect content area. Extending size for
// adornments is done by drawNativeControl subsequently.
