Abstract Device Context.
A Device Context is used to maintain the state of the graphics drawing system. Defining your drawing code in terms of the Abstract Device Context allows the drawing commands to be rendered on different types of surfaces, such as windows and images (FXDCWindow), or on paper (FXDCPrint). WYSYWYG may be obtained by using the same identical drawing code in your application regardless of the actual device surface being utilized.

Draw arcs.
The argument ang1 specifies the start of the arc relative to the three-o'clock position from the center, in units of degrees*64. The argument ang2 specifies the path and extent of the arc relative to the start of the arc, in units of degrees*64. The arguments x,y,w,h specify the bounding rectangle.
Reimplemented in FX::FXDCPrint, and FX::FXDCWindow.

Set dash pattern and dash offset.
A dash pattern of [1 2 3 4] is a repeating pattern of 1 foreground pixel, 2 background pixels, 3 foreground pixels, and 4 background pixels. The offset is where in the pattern the system will start counting. The maximum length of the dash pattern is 32.
Reimplemented in FX::FXDCPrint, and FX::FXDCWindow.
