xfarc - fill a part of an ellipse

### Calling Sequence

  `xfarc(x,y,w,h,a1,a2)`

### Parameters

- `x,y,w,h` : four real values defining a rectangle.
- `a1,a2` : real values defining a sector.

### Description

`xfarc` fills a part of an ellipse contained in the rectangle `(x,y,w,h)` (upper-left point, width, height), and in the sector defined by the angle `alpha1` and the angle `alpha1+alpha2` . `alpha1` and `alpha2` are given respectively by `a1/64` degrees and `a2/64` degrees. This function uses the current color and graphics scale.

### Examples

    // isoview scaling
    plot2d(0,0,-1,"031"," ",[-2,-2,2,2])
    xfarc(-0.5,0.5,1,1,0,90*64)
    xset("color",2)
    xfarc(0.5,0.5,1,1,0,360*64)
