asymptote: Drawing commands

 
 4 Drawing commands
 ******************
 
 All of 'Asymptote''s graphical capabilities are based on four primitive
 commands.  The three 'PostScript' drawing commands 'draw', 'fill', and
 'clip' add objects to a picture in the order in which they are executed,
 with the most recently drawn object appearing on top.  The labeling
 command 'label' can be used to add text labels and external EPS images,
 which will appear on top of the 'PostScript' objects (since this is
 normally what one wants), but again in the relative order in which they
 were executed.  After drawing objects on a picture, the picture can be
 output with the 'shipout' function (shipout).
 
    If you wish to draw 'PostScript' objects on top of labels (or
 verbatim 'tex' commands; tex), the 'layer' command may be used
 to start a new 'PostScript/LaTeX' layer:
 void layer(picture pic=currentpicture);
 
    The 'layer' function gives one full control over the order in which
 objects are drawn.  Layers are drawn sequentially, with the most recent
 layer appearing on top.  Within each layer, labels, images, and verbatim
 'tex' commands are always drawn after the 'PostScript' objects in that
 layer.
 
    While some of these drawing commands take many options, they all have
 sensible default values (for example, the picture argument defaults to
 currentpicture).
