ePiX creates line drawings, not pixmaps. In an eepic file,
objects are either pointlike (LATEX glyphs, text boxes) or pathlike
(everything else). The appearance of a pathlike object depends on the
line style, width, filling, and color. Each attribute
is a declaration, remaining in effect until superceded or the file
ends. When a file starts, paths are drawn solid, black, unfilled, and
with thinlines (a width of 
pt) in effect.
Attribute-setting commands should come in the figure body.
