/**

<heading>Class Description</heading>
|
||||
<p>
|
||||
This is a simple class used for encapsulating common drawing behaviors.
|
||||
These methods stndardize drawing of buttons, borders and other common
|
||||
gui elements. The drawing functions are encapsulated in a class to
|
||||
allow overridding of the methods so that these elements can be drawn
|
||||
in different ways (e.g. with themes).
|
||||
</p>
|
||||
<p>
|
||||
All the methods use the standard configurable colors defined in NSColor,
|
||||
such as <code>controlLightHighlightColor</code>,
|
||||
<code>controlShadowColor</code> and <code>controlDarkShadowColor</code>.

||||
