Re: Pieslice

A pieslice is, IMO, always closed. It would be a slice of an ellipse or a
circle. I'd think it would be used commonly enough, esp. for pie charts. A
keyword, arc, would designate an arc of a circle or ellipse.

In general, wouldn't it be nicest to offer a full range of predefined shapes,
including triangles, regular polygons, and starbursts, along with shapes
common to various kinds of diagrams, such as organizational charts,
flowcharts, maps, and engineering and electrical diagrams? These would offer
ease of use for new, non-artist, users. These would provide structures within
the language that support and mirror features in many common software packages
(insert favorite drawing/publishing/office program here). 

After all, isn't the idea behind SVG and other web formats to provide standard
file formats in which all applications can transfer information? It seems to
me that someday programs might use HTML, XML, CSS, SVG, PNG, or other formats
as their primary, native file formats. 

Specifically for pieslice:

I'd think most designers would want the ability to specify a pieslice by a
bounding box that defines the circle or ellipse and center point, as well as
entering the starting and ending angles of the slice's arc. 

Alternatively, a designer might want to enter the three points (center point,
starting point, and ending point) that define the pieslice. The relationship
of the starting and ending points to the center point would determine whether
the slice looks more like a triangle or like a circle minus a triangle.
