public class LLDWPainter
extends java.lang.Object
The equivalent of embedded structures and enumerations are LLDWPainter.DrawingFlip and LLDWPainter.DrawingCap. They are used
to identify the kind of drawing. Additionally, these methods requires MicroUIImage,
MicroUIGraphicsContext and MicroUIImageFormat classes.
The methods implementations follow the same rules than LLUIPainter (main important thing is to use the
framework object LLUIDisplay.Instance as monitor to synchronize drawings).

The center of the arc is defined as the center of the square whose origin is at (x,y) (upper-left corner) and whose dimension is given by diameter.
Angles are interpreted such that 0 degrees is at the 3 o'clock position. A positive value indicates a counter-clockwise rotation while a negative value indicates a clockwise rotation.
If diameter is negative or zero, nothing is drawn.
The angles are given relative to the square. For instance an angle of 45 degrees is always defined by the line from the center of the square to the upper right corner of the square. Thus for a non squared square angles are skewed along either height or width.

The rotation is specified by the center and the angle. The reference point is the graphical object top-left corner. The rotation point is relative where the graphical object will be drawn.
This method uses the nearest neighbor algorithm to render the content. This algorithm is faster than bilinear algorithm but its rendering is faster.
